#[repr(u32)]pub enum ChildType {
    ParentKeyId,
}

[−] Expand description

Type of child. It does not strictly define different child type, it can also be related to technical consideration or api variant.

Variants

ParentKeyId

[−] Expand description

If runtime module ensures that the child key is a unique id that will only be used once, its parent key is used as a child trie unique id.

Implementations

impl ChildType[−]

pub fn new(repr: u32) -> Option<ChildType>[−]

Try to get a child type from its u32 representation.

pub fn from_prefixed_key(
    storage_key: &'a PrefixedStorageKey
) -> Option<(ChildType, &'a [u8])>[−]

Transform a prefixed key into a tuple of the child type and the unprefixed representation of the key.

pub fn parent_prefix(&self) -> &'static [u8][−]

Returns the location reserved for this child trie in their parent trie if there is one.
