Expand description
The span(s) associated to a use of a place.
Variants§
ClosureUse
The access is caused by capturing a variable for a closure.
Fields
closure_kind: ClosureKind
This is true if the captured variable was from a coroutine.
FnSelfUse
The access is caused by using a variable as the receiver of a method that takes ‘self’
Fields
PatUse(Span)
This access is caused by a match
or if let
pattern.
OtherUse(Span)
This access has a single span associated to it: common case.

err: &mut Diag<'_>,
f: impl FnOnce(Span) -> CaptureArgLabel,
)
pub(crate) fn args_subdiag( self, err: &mut Diag<'_>, f: impl FnOnce(Span) -> CaptureArgLabel, )
Add a span label to the arguments of the closure, if it exists.

self,
err: &mut Diag<'_>,
action: InitializationRequiringAction,
)
pub(crate) fn var_path_only_subdiag( self, err: &mut Diag<'_>, action: InitializationRequiringAction, )
Add a span label to the use of the captured variable, if it exists.
only adds label to the path_span

self,
err: &mut Diag<'_>,
kind: Option<BorrowKind>,
f: impl FnOnce(ClosureKind, Span) -> CaptureVarCause,
)
pub(crate) fn var_subdiag( self, err: &mut Diag<'_>, kind: Option<BorrowKind>, f: impl FnOnce(ClosureKind, Span) -> CaptureVarCause, )
Add a subdiagnostic to the use of the captured variable, if it exists.
sourcepub(crate) fn for_closure(&self) -> bool
pub(crate) fn for_closure(&self) -> bool
Returns false
if this place is not used in a closure.
sourcepub(crate) fn for_coroutine(&self) -> bool
pub(crate) fn for_coroutine(&self) -> bool
Returns false
if this place is not used in a coroutine.
