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.

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.

Trait Implementations

impl Clone for PlaceContext

fn clone(&self) -> PlaceContext

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PlaceContext

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

Formats the value using the given formatter.

impl PartialEq<PlaceContext> for PlaceContext

fn eq(&self, other: &PlaceContext) -> bool

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
