Struct Sealed

pub struct Sealed<T> {
    inner: T,
    seal: FixedBytes<32>,
}

A consensus hashable item, with its memoized hash.

We do not implement any specific hashing algorithm here. Instead types implement the Sealable trait to provide define their own hash.

Fields

inner: T

seal: FixedBytes<32>
