Trait XofAlgorithm

pub trait XofAlgorithm {
    const SECURITY_LEVEL: usize;
    const MIN_OUTPUT_SIZE: usize;
    const MAX_OUTPUT_SIZE: Option<usize>;

Trait for XOF algorithms with compile-time guarantees

Required Associated Constants

const SECURITY_LEVEL: usize

Security level in bits

const MIN_OUTPUT_SIZE: usize

Minimum recommended output size in bytes

const MAX_OUTPUT_SIZE: Option<usize>

Maximum output size in bytes (None for unlimited)

const ALGORITHM_ID: &'static str

Algorithm identifier

Provided Methods

fn name() -> &'static str

Algorithm name

fn validate_output_length(len: usize) -> Result<()>

Validate output length

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.
