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

Specifies the source of the value(s) to be pushed onto the advice stack.

Variants§

§

Value(Felt)

Puts a single value onto the advice stack.

§

Map

Fields

§key: Word
§include_len: bool

Fetches a list of elements under the specified key from the advice map and pushes them onto the advice stack.

If include_len is set to true, this also pushes the number of elements ont the advice stack.

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

Example

Given an advice stack [a, b, c, ...], and a map x |-> [d, e, f]:

A call push_stack(AdviceSource::Map { key: x, include_len: false }) will result in advice stack: [d, e, f, a, b, c, ...].

A call push_stack(AdviceSource::Map { key: x, include_len: true }) will result in advice stack: [3, d, e, f, a, b, c, ...].

Errors

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