Struct Blake3XofReader 

pub struct Blake3XofReader { /* private fields */ }

BLAKE3 extensible-output function (XOF) reader.

Produced by Blake3::finalize_xof. Implements the Xof trait.

Note: a BLAKE3 XOF is an output stream, so Xof::absorb is a no-op and any bytes passed to it are silently ignored. Add input through Blake3::update before finalizing instead.

use crypto::{blake3::Blake3, Xof};

let mut hasher = Blake3::new();
hasher.update(b"hello world");
let mut xof = hasher.finalize_xof();
let mut out = [0u8; 64];
xof.squeeze(&mut out);

When the zeroize feature is enabled, the retained root/node state — which for a keyed hash includes key material — is overwritten with zeros when the reader is dropped.

Trait Implementations

impl Clone for Blake3XofReader

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Drop for Blake3XofReader

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Xof for Blake3XofReader

fn absorb(&mut self, _data: &[u8])

No-op: a XOF reader cannot absorb data. Any bytes passed here are ignored; pass them to Blake3::update before finalizing instead.

fn squeeze(&mut self, out: &mut [u8])

Fill out with bytes.

impl Zeroize for Blake3XofReader

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
