Crate sp_runtime

Runtime Modules shared primitive types.

Re-exports

pub use random_number_generator::RandomNumberGenerator;

Modules

biguint	Re-export big_uint stuff. Infinite precision unsigned integer for substrate runtime.
curve	Provides some utilities to define a piecewise linear function.
generic	Generic implementations of Extrinsic/Header/Block.
helpers_128bit	Re-export 128 bit helpers. Some helper functions to work with 128bit numbers. Note that the functionality provided here is only sensible to use with 128bit numbers because for smaller sizes, you can always rely on assumptions of a bigger type (u128) being available, or simply create a per-thing and use the multiplication implementation provided there.
key_types	Re-export this since it's part of the API of this crate. Known key types; this also functions as a global registry of key types for projects wishing to avoid collisions with each other.
offchain	A collection of higher lever helpers for offchain calls.
random_number_generator	A simple pseudo random number generator that allows a stream of random numbers to be efficiently created from a single initial seed hash.
testing	Testing utilities.
traits	Primitives for the runtime modules.
transaction_validity	Transaction validity interface.

Macros

__impl_outer_config_types	Helper macro for impl_outer_config
assert_eq_error_rate	Checks that $x is equal to $y with an error rate of $error.
count	Calls a given macro a number of times with a set of fixed params and an incrementing numeral. e.g.
create_runtime_str	Create a const RuntimeString.
impl_opaque_keys	Implement OpaqueKeys for a described struct.
impl_outer_config	Implement the output "meta" module configuration struct, which is basically: pub struct GenesisConfig { rust_module_one: Option, ... }

Structs

AccountId32	Re-export this since it's part of the API of this crate. An opaque 32-byte cryptographic identifier.
AnySignature	Signature verify that can work with any known signature types..
CryptoTypeId	Re-export this since it's part of the API of this crate. An identifier for a specific cryptographic algorithm used by a key pair
Digest	Generic header digest.
DispatchErrorWithPostInfo	Result of a Dispatchable which contains the DispatchResult and additional information about the Dispatchable that is only known post dispatch.
FixedI64	Re-export top-level arithmetic stuff. A fixed point number representation in the range.
FixedI128	Re-export top-level arithmetic stuff. A fixed point number representation in the range.
FixedU128	Re-export top-level arithmetic stuff. A fixed point number representation in the range.
KeyTypeId	Re-export this since it's part of the API of this crate. An identifier for a type of cryptographic key.
ModuleId	A module identifier. These are per module and should be stored in a registry somewhere.
OpaqueExtrinsic	Simple blob to hold an extrinsic without committing to its format and ensure it is serialized correctly.
PerU16	Re-export top-level arithmetic stuff. A fixed point representation of a number in the range [0, 1].
Perbill	Re-export top-level arithmetic stuff. A fixed point representation of a number in the range [0, 1].
Percent	Re-export top-level arithmetic stuff. A fixed point representation of a number in the range [0, 1].
Permill	Re-export top-level arithmetic stuff. A fixed point representation of a number in the range [0, 1].
Perquintill	Re-export top-level arithmetic stuff. A fixed point representation of a number in the range [0, 1].
Rational128	Re-export top-level arithmetic stuff. A wrapper for any rational number with a 128 bit numerator and denominator.
SignatureBatching	Batching session.
Storage	Struct containing data needed for a storage.
StorageChild	Child trie storage data.

Enums

DigestItem	Digest item that is able to encode/decode 'system' digest items and provide opaque access to other items.
DispatchError	Reason why a dispatch call failed.
Either	The enum Either with variants Left and Right is a general purpose sum type with two cases.
MultiSignature	Signature verify that can work with any known signature types..
MultiSigner	Public key for any known crypto algorithm.
RuntimeString	A string that wraps a &'static str in the runtime and String/Vec<u8> on decode.

Traits

BoundToRuntimeAppPublic	Something that bound to a fixed RuntimeAppPublic.
BuildModuleGenesisStorage	Something that can build the genesis storage of a module.
BuildStorage	Complex storage builder stuff.
CryptoType	Re-export this since it's part of the API of this crate. Type which has a particular kind of crypto associated with it.
Deserialize	A data structure that can be deserialized from any data format supported by Serde.
DeserializeOwned	A data structure that can be deserialized without borrowing any data from the deserializer.
FixedPointNumber	Re-export top-level arithmetic stuff. Something that implements a decimal fixed point number.
FixedPointOperand	Re-export top-level arithmetic stuff. Integer types that can be used to interact with FixedPointNumber implementations.
PerThing	Re-export top-level arithmetic stuff. Something that implements a fixed point ration with an arbitrary granularity X, as parts per X.
RuntimeAppPublic	A runtime interface for an application's public key.
SaturatedConversion	Re-export top-level arithmetic stuff. Convenience type to work around the highly unergonomic syntax needed to invoke the functions of overloaded generic traits, in this case SaturatedFrom and SaturatedInto.
Serialize	A data structure that can be serialized into any data format supported by Serde.
TypeId	Re-export this since it's part of the API of this crate. Provide a simple 4 byte identifier for a type.

Functions

print	Print something that implements Printable from the runtime.
verify_encoded_lazy	Verify a signature on an encoded value in a lazy manner. This can be an optimization if the signature scheme has an "unsigned" escape hash.

Type Definitions

ApplyExtrinsicResult	The result of applying of an extrinsic.
ApplyExtrinsicResultWithInfo	Same as ApplyExtrinsicResult but augmented with PostDispatchInfo on success.
ConsensusEngineId	Consensus engine unique ID.
DispatchOutcome	This type specifies the outcome of dispatching a call to a module.
DispatchResult	This is the legacy return type of Dispatchable. It is still exposed for compatibility reasons. The new return type is DispatchResultWithInfo. FRAME runtimes should use frame_support::dispatch::DispatchResult.
DispatchResultWithInfo	Return type of a Dispatchable which contains the DispatchResult and additional information about the Dispatchable that is only known post dispatch.
InnerOf	Re-export top-level arithmetic stuff. Get the inner type of a PerThing.
Justification	An abstraction over justification for a block's validity under a consensus algorithm.
