Struct Flag 

pub struct Flag {
    pub id: String,
    pub description: Option<String>,
    pub variants: Vec<Variant>,
    pub default_variant: Variant,
    pub rules: Vec<Rule>,
    pub enabled: bool,
}

A single flag.

Fields

id: String

Stable flag identifier (also the public name).

description: Option<String>

Free-form description.

variants: Vec<Variant>

All possible variant names. Rules + the default must reference values from this list.

default_variant: Variant

Variant returned when no rule matches.

rules: Vec<Rule>

Ordered targeting rules.

enabled: bool

When false, the evaluator skips all rules and returns default_variant. Useful as a kill switch.
