Struct SymbolTable 

pub struct SymbolTable<'src> { /* private fields */ }

Collected symbols and imports from a PHP source file.

Implementations

impl<'src> SymbolTable<'src>

pub fn build<'arena>(program: &Program<'arena, 'src>) -> Self

Walk the program AST and extract all declarations.

pub fn symbols(&self) -> &[Symbol<'src>]

All collected symbols.

pub fn imports(&self) -> &[UseImport<'src>]

All use imports.

pub fn symbols_of_kind( &self, kind: SymbolKind, ) -> impl Iterator<Item = &Symbol<'src>>

Iterate symbols of a specific kind.

pub fn find_by_fqn(&self, fqn: &str) -> Option<&Symbol<'src>>

Find a symbol by its fully qualified name.

pub fn symbols_at(&self, offset: u32) -> Vec<&Symbol<'src>>

Find all symbols at a given byte offset (i.e. whose span contains the offset).

pub fn resolve_name(&self, name: &str) -> Option<&str>

Resolve a simple (unqualified) name using the imports and current namespace. Returns the FQN if found, None otherwise.

pub fn functions(&self) -> impl Iterator<Item = &Symbol<'src>>

Convenience: all functions.

pub fn classes(&self) -> impl Iterator<Item = &Symbol<'src>>

Convenience: all classes.

pub fn interfaces(&self) -> impl Iterator<Item = &Symbol<'src>>

Convenience: all interfaces.

pub fn traits(&self) -> impl Iterator<Item = &Symbol<'src>>

Convenience: all traits.

pub fn enums(&self) -> impl Iterator<Item = &Symbol<'src>>

Convenience: all enums.

pub fn constants(&self) -> impl Iterator<Item = &Symbol<'src>>

Convenience: all constants.

pub fn members_of<'a>( &'a self, parent_fqn: &'a str, ) -> impl Iterator<Item = &'a Symbol<'src>>

Get all members (methods, properties, class constants, enum cases) of a given parent FQN.
