A detected feature flag use site.

Fields

path: PathBuf

File containing the feature flag usage.

flag_name: String

Name or identifier of the flag (e.g., ENABLE_NEW_CHECKOUT, new-checkout).

kind: FlagKind

How the flag was detected.

confidence: FlagConfidence

Detection confidence level.

line: u32

1-based line number.

col: u32

0-based byte column offset.

guard_span_start: Option<u32>

Start byte offset of the guarded code block (if-branch span), if detected.

guard_span_end: Option<u32>

End byte offset of the guarded code block (if-branch span), if detected.

sdk_name: Option<String>

SDK or provider name (e.g., “LaunchDarkly”, “Statsig”), if detected from SDK call.

guard_line_start: Option<u32>

Line range of the guarded code block (derived from guard_span + line_offsets). Used for cross-reference with dead code findings.

guard_line_end: Option<u32>

End line of the guarded code block.

guarded_dead_exports: Vec<String>

Unused exports found within the guarded code block. Populated by cross-reference with dead code analysis.
