Trait FindAuthor

pub trait FindAuthor<Author> {
    // Required method
    fn find_author<'a, I>(digests: I) -> Option<Author>
       where I: 'a + IntoIterator<Item = (ConsensusEngineId, &'a [u8])>;
}

A trait for finding the author of a block header based on the PreRuntime digests contained within it.

Required Methods

where I: 'a + IntoIterator<Item = (ConsensusEngineId, &'a [u8])>,

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
