Implementations§

source§

impl UnsafeOpKind

source

pub fn emit_unsafe_op_in_unsafe_fn_lint( &self, tcx: TyCtxt<'_>, hir_id: HirId, span: Span )

Trait Implementations§

source§

impl Clone for UnsafeOpKind

source§

fn clone(&self) -> UnsafeOpKind

Returns a copy of the value. Read more
1.0.0 · source§

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

Performs copy-assignment from source. Read more
source§

impl PartialEq<UnsafeOpKind> for UnsafeOpKind

source§

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

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

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.

Performs the conversion.

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.
