Struct sp_runtime::KeyTypeId

pub struct KeyTypeId(pub [u8; 4]);

Re-export this since it’s part of the API of this crate. An identifier for a type of cryptographic key.

To avoid clashes with other modules when distributing your module publicly, register your KeyTypeId on the list here by making a PR.

Values whose first character is _ are reserved for private use and won’t conflict with any public modules.

impl Default for KeyTypeId

fn default() -> KeyTypeId

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for KeyTypeId

fn deserialize<__D>(
    __deserializer: __D
) -> Result<KeyTypeId, <__D as Deserializer<'de>>::Error>where
    __D: Deserializer<'de>,

impl Encode for KeyTypeId

fn encode_to<__CodecOutputEdqy>(&self, __codec_dest_edqy: &mut __CodecOutputEdqy)where
    __CodecOutputEdqy: Output + ?Sized,

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8, Global>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> Rwhere
    F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl From<u32> for KeyTypeId

fn hash<__H>(&self, state: &mut __H)where
    __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

impl Ord for KeyTypeId

fn cmp(&self, other: &KeyTypeId) -> Ordering

This method returns an Ordering between self and other.
