Trait FixedOutput

pub trait FixedOutput:
    Sized
    + Update
    + OutputSizeUser {
    // Required method
    fn finalize_into(self, out: &mut GenericArray<u8, Self::OutputSize>);

    // Provided method
    fn finalize_fixed(self) -> GenericArray<u8, Self::OutputSize> { ... }
}

Trait for hash functions with fixed-size output.

Required Methods

fn finalize_into(self, out: &mut GenericArray<u8, Self::OutputSize>)

Consume value and write result into provided array.

Provided Methods

fn finalize_fixed(self) -> GenericArray<u8, Self::OutputSize>

Retrieve result and consume the hasher instance.

Dyn Compatibility

This trait is not dyn compatible.

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