Struct BodySourceMap 

pub struct BodySourceMap { /* private fields */ }

Maps every ExprId/StmtId back to its source byte range. The reverse direction (offset → ExprId) is the tightest containing expression.

Implementations

impl BodySourceMap

pub fn expr_range(&self, id: ExprId) -> TextRange

The source range of an expression.

pub fn stmt_range(&self, id: StmtId) -> TextRange

The source range of a statement (the whole statement node — the UNREACHABLE_CODE anchor).

pub fn expr_at_offset(&self, offset: u32) -> Option<ExprId>

The innermost (tightest) expression whose range contains offset.

pub fn expr_for_range(&self, range: TextRange) -> Option<ExprId>

The expression whose range exactly equals range (for mapping a CST node back to its ExprId — e.g. a member-completion receiver).

Trait Implementations

impl Clone for BodySourceMap

fn clone(&self) -> BodySourceMap

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BodySourceMap

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

Formats the value using the given formatter.

impl Default for BodySourceMap

fn default() -> BodySourceMap

Returns the “default value” for a type.

impl Eq for BodySourceMap

impl PartialEq for BodySourceMap

fn eq(&self, other: &BodySourceMap) -> 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.
