Struct NameResolver 

pub struct NameResolver { /* private fields */ }

Tracks the current namespace and use imports and resolves names against them.

Feed every statement to observe_stmt in source order (e.g. from ScopeVisitor::visit_stmt), then call resolve_name. Imports are cleared at each namespace statement; they are not popped at the end of a braced namespace block.

Builtin type names (int, string, …) are not special-cased.

Implementations

impl NameResolver

pub fn new() -> Self

Creates a resolver in the global namespace with no imports.

pub fn namespace(&self) -> Option<&str>

Current namespace, or None for the global namespace.

pub fn enter_namespace(&mut self, namespace: Option<&str>)

Enters namespace and clears all imports.

pub fn add_import(&mut self, kind: UseKind, fqn: &str, alias: Option<&str>)

Registers an import. fqn may carry a leading backslash; alias defaults to the last segment of fqn.

pub fn observe_stmt(&mut self, stmt: &Stmt<'_, '_>)

Updates state for namespace and use statements; ignores everything else.

pub fn observe_owned_stmt(&mut self, stmt: &Stmt)

Owned-AST counterpart of observe_stmt.

pub fn resolve_name( &self, name: &Name<'_, '_>, ctx: NameContext, ) -> ResolvedName

Resolves a borrowed-AST name.

pub fn resolve_owned_name(&self, name: &Name, ctx: NameContext) -> ResolvedName

Resolves an owned-AST name.

pub fn resolve<S: AsRef<str>>( &self, ctx: NameContext, kind: NameKind, parts: &[S], ) -> ResolvedName

Resolves a name given as its kind and \-separated segments.
