Struct ParseOutput 

pub struct ParseOutput(/* private fields */);

Memoised result of parsing a SourceFile.

Wraps an Arc<Parse>; equality is by pointer identity so that Salsa can detect when re-parsing produced the same tree.

Implementations

impl ParseOutput

pub fn parse(&self) -> &Parse

Access the underlying Parse.

pub fn strong_count(&self) -> usize

Strong-reference count of the wrapped Arc<Parse>.

Exposed so tests and memory-diagnostics tooling can observe Salsa memo retention (§11.6): after a FileId is evicted and the next revision replaces the memo entry for its SourceFile, the old ParseOutput held by the memo is dropped and any caller-held clone of its Arc<Parse> sees its strong count drop to 1.

Trait Implementations

impl Clone for ParseOutput

fn clone(&self) -> ParseOutput

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseOutput

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

Formats the value using the given formatter.

impl PartialEq for ParseOutput

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