Struct sp_runtime::KeyTypeId

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

Expand description

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.
