Struct Builtin 

pub struct Builtin {
    pub id: &'static str,
    pub display_name: &'static str,
    pub severity: Severity,
    pub regex_src: &'static str,
    pub regex: OnceLock<Regex>,
    pub metadata: Option<PatternMetadata>,
    pub rotation: Option<RotationSpec>,
    pub liveness: Option<LivenessSpec>,
}

Adapter struct that turns a static data row into a SecretPattern implementation. Each BUILTINS entry is a Builtin; the regex compiles lazily on first access via OnceLock so process startup pays nothing for patterns that are never consulted.

Fields

id: &'static str

Stable identifier (lowercase kebab-case).

display_name: &'static str

Human-readable name.

severity: Severity

Severity to attach to a leak finding.

regex_src: &'static str

Regex source — compiled lazily into Builtin::regex.

regex: OnceLock<Regex>

Lazily-compiled regex. Use Builtin::compiled_regex in preference to touching this field directly.

metadata: Option<PatternMetadata>

Optional descriptive metadata (provider id, retrieval URL, expiry default, scope hints).

rotation: Option<RotationSpec>

Optional rotation hint. None for v1; populated when P2.4 wires inheritance.

liveness: Option<LivenessSpec>

Optional liveness probe. None for v1; populated when P9.2 adds provider liveness checks.

Trait Implementations

impl SecretPattern for Builtin

fn id(&self) -> &str

Stable identifier (lowercase, kebab-case). Used as a foreign key from the global index entry’s pattern_id (ADR-020 §3) and as a join key with other tools that consume the catalogue.

fn display_name(&self) -> &str

Human-readable name shown in secrets describe and in scan-tool reports.

fn severity(&self) -> Severity

Severity to attach to a leak finding for this pattern.

fn format_regex(&self) -> &Regex

Regular expression matching valid values of this kind.

fn metadata(&self) -> Option<&PatternMetadata>

Optional descriptive metadata (provider, retrieval URL, expiry, scopes).

fn rotation(&self) -> Option<&RotationSpec>

Optional rotation hint (manual vs provider-driven).

fn liveness(&self) -> Option<&LivenessSpec>

Optional liveness probe specification.
