Enum rustc_middle::mir::Safety

pub enum Safety {
    Safe,
    BuiltinUnsafe,
    FnUnsafe,
    ExplicitUnsafe(HirId),
}

Variants

Safe

BuiltinUnsafe

Unsafe because of compiler-generated unsafe code, like await desugaring

FnUnsafe

Unsafe because of an unsafe fn

ExplicitUnsafe

Unsafe because of an unsafe block

Trait Implementations

impl Clone for Safety

fn clone(&self) -> Safety

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Safety

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

Formats the value using the given formatter.

impl<'tcx, __D: TyDecoder<'tcx>> Decodable<__D> for Safety

fn decode(__decoder: &mut __D) -> Result<Self, <__D as Decoder>::Error>

impl<'tcx, __E: TyEncoder<'tcx>> Encodable<__E> for Safety

impl PartialEq<Safety> for Safety

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

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

Layout

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