Expand description

A view that supports hashing its values.

Required Associated Types§

source

type Hasher: Hasher

How to compute hashes.

Required Methods§

source

fn hash_mut<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<<Self::Hasher as Hasher>::Output, ViewError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Computes the hash of the values.

Implementations do not need to include a type tag. However, the usual precautions to enforce collision resistance must be applied (e.g. including the length of a collection of values).
