pub struct PrecompileCommitment { /* private fields */ }Expand description
A commitment to the evaluation of PrecompileRequest, representing both the input and result
of the request.
This structure contains both the tag (which includes metadata like event ID) and the commitment to the input and result (calldata) of the precompile request.
§Tag Structure
The tag is a 4-element word [event_id, meta1, meta2, meta3] where:
- First element: The
EventIdfrom the correspondingEventHandler - Remaining 3 elements: Available for precompile-specific metadata (e.g.,
len_bytesfor hash functions to distinguish actual data from padding)
Implementations§
Source§impl PrecompileCommitment
impl PrecompileCommitment
Sourcepub fn new(tag: Word, comm: Word) -> PrecompileCommitment
pub fn new(tag: Word, comm: Word) -> PrecompileCommitment
Creates a new precompile commitment from a TAG and COMM.
TAG: 4-element word where the first element encodes theEventId; the remaining elements are available as precompile-specific metadata (e.g.,len_bytes).COMM: 4-element word containing the commitment to the calldata (or handler-specific witness) for this precompile request.
Sourcepub fn tag(&self) -> Word
pub fn tag(&self) -> Word
Returns the TAG word which encodes the EventId in the first element and optional
precompile-specific metadata in the remaining three elements.
Sourcepub fn comm_calldata(&self) -> Word
pub fn comm_calldata(&self) -> Word
Returns the COMM word (calldata commitment), i.e., the commitment to the precompile’s
calldata (or other handler-specific witness).
Sourcepub fn to_elements(&self) -> [BaseElement; 8]
pub fn to_elements(&self) -> [BaseElement; 8]
Returns the concatenation of TAG and COMM as field elements.
