[−][src]Trait sp_runtime::traits::AccountIdConversion

pub trait AccountIdConversion<AccountId>: Sized {
    fn into_sub_account<S: Encode>(&self, sub: S) -> AccountId;

    fn try_from_sub_account<S: Decode>(x: &AccountId) -> Option<(Self, S)>;

    fn into_account(&self) -> AccountId { ... }

    fn try_from_account(a: &AccountId) -> Option<Self> { ... }
}

This type can be converted into and possibly from an AccountId (which itself is generic).

Required methods

fn into_sub_account<S: Encode>(&self, sub: S) -> AccountId

Convert this value amalgamated with the a secondary "sub" value into an account ID. This is infallible.

NOTE: The account IDs from this and from into_account are not guaranteed to be distinct for any given value of self, nor are different invocations to this with different types T. For example, the following will all encode to the same account ID value:

  • self.into_sub_account(0u32)
  • self.into_sub_account(vec![0u8; 0])
  • self.into_account()

fn try_from_sub_account<S: Decode>(x: &AccountId) -> Option<(Self, S)>

Try to convert an account ID into this type. Might not succeed.

Provided methods

fn into_account(&self) -> AccountId

Convert into an account ID. This is infallible.

fn try_from_account(a: &AccountId) -> Option<Self>

Try to convert an account ID into this type. Might not succeed.

Implementors

impl<T: Encode + Decode + Default, Id: Encode + Decode + TypeId> AccountIdConversion<T> for Id[src]

Format is TYPE_ID ++ encode(parachain ID) ++ 00.... where 00... is indefinite trailing zeroes to fill AccountId.
