Struct AuthorityIndex

Source 
pub struct AuthorityIndex(/* private fields */);
Expand description

Each authority is uniquely identified by its AuthorityIndex in the Committee. AuthorityIndex is between 0 (inclusive) and the total number of authorities (exclusive) limited by u8 to 255.

NOTE: for safety, invalid AuthorityIndex should be impossible to create. So AuthorityIndex should not be created or incremented outside of this file. AuthorityIndex received from peers should be validated before use.
