FeatureRecord

Struct FeatureRecord 

Source
pub struct FeatureRecord {
    pub section_name: String,
    pub enabled: bool,
    pub override_source: Option<OverrideSource>,
    pub requires: &'static [&'static str],
    pub metadata: Box<FeatureMetadata>,
}
Expand description

A snapshot of one optional feature’s resolved state.

Collected by crate::FeatureRegistry as each feature is loaded, so the registry can produce a startup summary of every registered feature.

Construct via crate::FeatureRecordBuilder rather than struct literal syntax, as new fields may be added without a semver bump.

Fields§

§section_name: String

The TOML section key for this feature (e.g. "message_broker").

§enabled: bool

Whether the feature resolved to enabled after applying all precedence rules.

§override_source: Option<OverrideSource>

Which external control overrode the natural TOML state, if any.

§requires: &'static [&'static str]

Section keys this feature declared it depends on via crate::OptionalSection::requires.

§metadata: Box<FeatureMetadata>

Static annotations (description, owner, deprecation) declared by the feature via crate::OptionalSection::metadata.
