Module utils 

Utilities for hash circuit examples

Structs

HasherInstance

Instance (witness) parameters shared by every hasher example.

HasherParams

Circuit-shape parameters shared by every hasher example.

Enums

HasherMode

The gadget shape selected by HasherParams.

Constants

DEFAULT_HASH_MESSAGE_BYTES

Default message size for hash circuit examples (1 KiB)

DEFAULT_RANDOM_SEED

Standard seed for reproducible random message generation

Functions

hasher_param_summary

One-line summary of the circuit shape selected by HasherParams, for stat output.

pack_bytes_u32words

Pack message bytes into 32-bit words, one word per wire with the high 32 bits zero.

pack_bytes_u64words

Pack message bytes into 64-bit words, one word per wire.

resolve_hasher_message

Resolve a HasherInstance into the concrete message bytes to hash, validated against mode.

resolve_hasher_mode

Resolve HasherParams into the gadget shape the circuit should be built from.
