Struct StageCandidate 

pub struct StageCandidate {
    pub name: String,
    pub overhead_tokens: u32,
    pub savings_tokens: u32,
    pub applicable: bool,
}

Minimum Description Length (MDL) stage selection.

MDL principle (Rissanen 1978): the best compression is the one that minimizes description_length(model) + description_length(data|model).

Instead of running all 16 stages on every input, MDL selects the optimal subset of stages for each content type. Stages that add overhead (headers, legends) without sufficient compression are skipped. A stage candidate with its estimated cost and benefit.

Fields

name: String

Stage name.

overhead_tokens: u32

Estimated overhead in tokens (headers, legends, markers).

savings_tokens: u32

Estimated savings in tokens.

applicable: bool

Whether this stage is applicable to the content type.

Implementations

impl StageCandidate

pub fn net_benefit(&self) -> i32

Net benefit: savings minus overhead. Negative means the stage hurts.
