Struct TupleHash128 

pub struct TupleHash128 { /* private fields */ }

TupleHash128 implementation

Implementations

impl TupleHash128

pub fn new(custom: &[u8]) -> Self

Creates a new TupleHash instance with the given customization string

pub fn update_tuple<T: AsRef<[u8]>>(&mut self, tuple: &[T])

Update with a tuple of strings

pub fn update(&mut self, data: &[u8])

Update with a single string (for compatibility)

pub fn finalize(self, output: &mut [u8]) -> Option<()>

Finalize with specified output length.

output.len() must not exceed MAX_SP800185_FIXED_OUTPUT_BYTES. For longer output, use Self::xof.

Returns None if output.len() is greater than MAX_SP800185_FIXED_OUTPUT_BYTES.

pub fn finalize_with_length(self, output_len: usize) -> Option<Vec<u8>>

Finalize with specified output length and return as Vec.

Returns None if output_len is greater than MAX_SP800185_FIXED_OUTPUT_BYTES. For longer output, use Self::xof.

pub fn xof(self) -> TupleHash128Reader

Returns an XOF reader for variable-length output.

SP 800-185 encodes XOF mode with right_encode(0) (output bit length zero) before squeezing.

This consumes self and finalizes the sponge; you cannot call Self::update or Self::update_tuple afterward on this value.
