pub struct NoteInputs { /* private fields */ }
Expand description
A container for note inputs.
A note can be associated with up to 128 input values. Each value is represented by a single field element. Thus, note input values can contain up to ~1 KB of data.
All inputs associated with a note can be reduced to a single commitment which is computed by first padding the inputs with ZEROs to the next multiple of 8, and then by computing a sequential hash of the resulting elements.
Implementations§
Source§impl NoteInputs
impl NoteInputs
Sourcepub fn new(values: Vec<Felt>) -> Result<Self, NoteError>
pub fn new(values: Vec<Felt>) -> Result<Self, NoteError>
Returns NoteInputs instantiated from the provided values.
§Errors
Returns an error if the number of provided inputs is greater than 128.
Sourcepub fn commitment(&self) -> Digest
pub fn commitment(&self) -> Digest
Returns a commitment to these inputs.
Sourcepub fn num_values(&self) -> u8
pub fn num_values(&self) -> u8
Returns the number of input values.
The returned value is guaranteed to be smaller than or equal to 128.
Sourcepub fn format_for_advice(&self) -> Vec<Felt>
pub fn format_for_advice(&self) -> Vec<Felt>
Returns the note’s input formatted to be used with the advice map.
The format is INPUTS || PADDING
, where:
Where:
- INPUTS is the variable inputs for the note
- PADDING is the optional padding to align the data with a 2WORD boundary
