Struct Program 

pub struct Program {
    pub name: String,
    pub source: String,
    pub output_sample: String,
    pub standing_context: String,
    pub retries: usize,
}

A program representation to evaluate for token efficiency.

Fields

name: String

Identifier for the program (used in comparisons/reports).

source: String

The program text the agent writes.

output_sample: String

A representative output the agent reads back (empty if none).

standing_context: String

The schema/docs the model must carry to use it (empty if none).

retries: usize

Estimated retry tokens for this representation (0 = unambiguous).

Implementations

impl Program

pub fn new(name: impl Into<String>, source: impl Into<String>) -> Self

A program with just a name and source (no output/standing-context/retries).
