Function Documentation

pub fn keccak_f1600(
	input: &Matrix
) -> Result<Matrix>

Apply Keccak-f[1600] independently to every 200-byte row. Errors Rejects invalid shapes, dtypes, shader address limits, allocation or recording failures.

pub fn merkle_root(
	input: &Matrix
) -> Result<Matrix>

Reduce 32-byte leaf hashes to one Merkle root. Errors Rejects invalid shapes, dtypes, shader address limits, allocation or recording failures.

pub fn shake128(
	input: &Matrix,
	output_length: usize
) -> Result<Matrix>

Hash every row with SHAKE-128. An output_length of zero selects 16 bytes. Output rows are padded to an eight-byte boundary, matching the OA donor ABI. Errors Rejects invalid shapes, dtypes, shader address limits, allocation or recording failures.

pub fn shake256(
	input: &Matrix,
	output_length: usize
) -> Result<Matrix>

Hash every row with SHAKE-256. An output_length of zero selects 32 bytes. Output rows are padded to an eight-byte boundary, matching the OA donor ABI. Errors Rejects invalid shapes, dtypes, shader address limits, allocation or recording failures.
