pub enum AdviceSource {
    Value(Felt),
    Map {
        key: Word,
    },
}
Expand description

Placeholder for advice provider tape mutation.

Variants§

§

Value(Felt)

Writes a single value to the head of the advice tape.

§

Map

Fields

§key: Word

Fetch a keyed tape from the values map, reversing and appending it to the advice tape.

Note: this operation shouldn’t consume the map element so it can be called multiple times for the same key.

Example

Given an advice tape [a,b,c], and a map x |-> [d,e,f], a call write_tape_from_map(x) will result in [a,b,c,f,e,d] for the advice tape, and will preserve x |-> [d,e,f].

Errors

Returns an error if the key was not found in the key-value map.
