Implementations§

impl PlaceContext

pub fn is_drop(self) -> bool

Returns true if this place context represents a drop.

pub fn is_borrow(self) -> bool

Returns true if this place context represents a borrow, excluding fake borrows (which are an artifact of borrowck and not actually borrows in runtime MIR).

pub fn is_address_of(self) -> bool

Returns true if this place context represents an address-of.

pub fn is_storage_marker(self) -> bool

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

pub fn is_mutating_use(self) -> bool

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

pub fn is_use(self) -> bool

Returns true if this place context represents a use.

pub fn is_place_assignment(self) -> bool

Returns true if this place context represents an assignment statement.

pub fn ambient_variance(self) -> Variance

The variance of a place in the given context.
