Source location and whether the identifier is a JSXIdentifier.

Fields

start: u32

The byte offset of the identifier (base.start). Stored here so that callers iterating by node_id can still do position-range containment checks without a separate bridge map.

loc: SourceLocation

is_jsx: bool

opening_element_loc: Option<SourceLocation>

For JSX identifiers that are the root name of a JSXOpeningElement, stores the JSXOpeningElement’s loc (which spans the full tag).

is_declaration_name: bool

True if this identifier is the name of a function/class declaration (not an expression reference). Used by gather_captured_context to skip non-expression positions, matching the TS behavior where the Expression visitor doesn’t visit declaration names.

in_type_annotation: bool

True if this identifier sits inside a type annotation subtree (TypeAnnotation/TSTypeAnnotation/TypeAlias/TSTypeAliasDeclaration). gather_captured_context skips these to match the TS gatherCapturedContext traverse, which skips those subtrees; the hoisting analysis and FindContextIdentifiers do NOT skip them in TS.
