Methods

impl<'tcx> LvalueContext<'tcx>

fn is_drop(&self) -> bool

🔬 This is a nightly-only experimental API. (rustc_private)

Returns true if this lvalue context represents a drop.

fn is_storage_marker(&self) -> bool

🔬 This is a nightly-only experimental API. (rustc_private)

Returns true if this lvalue context represents a storage live or storage dead marker.

fn is_storage_live_marker(&self) -> bool

🔬 This is a nightly-only experimental API. (rustc_private)

Returns true if this lvalue context represents a storage live marker.

fn is_storage_dead_marker(&self) -> bool

🔬 This is a nightly-only experimental API. (rustc_private)

Returns true if this lvalue context represents a storage dead marker.

fn is_mutating_use(&self) -> bool

🔬 This is a nightly-only experimental API. (rustc_private)

Returns true if this lvalue context represents a use that potentially changes the value.

fn is_nonmutating_use(&self) -> bool

🔬 This is a nightly-only experimental API. (rustc_private)

Returns true if this lvalue context represents a use that does not change the value.

fn is_use(&self) -> bool

🔬 This is a nightly-only experimental API. (rustc_private)

Trait Implementations

impl<'tcx> Copy for LvalueContext<'tcx>

impl<'tcx> Clone for LvalueContext<'tcx>

fn clone(&self) -> LvalueContext<'tcx>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'tcx> Debug for LvalueContext<'tcx>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<'tcx> PartialEq for LvalueContext<'tcx>

fn eq(&self, __arg_0: &LvalueContext<'tcx>) -> bool

This method tests for self and other values to be equal, and is used by ==.
