Struct AstIdMap

pub struct AstIdMap { /* private fields */ }

Maps items’ SyntaxNodes to ErasedFileAstIds and back.

Implementations

impl AstIdMap

pub fn from_source(node: &SyntaxNode) -> AstIdMap

pub fn root(&self) -> SyntaxNodePtr

The [AstId] of the root node

pub fn ast_id<N: AstIdNode>(&self, item: &N) -> FileAstId<N>

pub fn ast_id_for_ptr<N: AstIdNode>(&self, ptr: AstPtr<N>) -> FileAstId<N>

pub fn get<N: AstIdNode>(&self, id: FileAstId<N>) -> AstPtr<N>

pub fn get_erased(&self, id: ErasedFileAstId) -> SyntaxNodePtr

Trait Implementations

impl Debug for AstIdMap

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for AstIdMap

fn default() -> AstIdMap

Returns the “default value” for a type.

impl PartialEq for AstIdMap

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
