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(HirId)

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<__D: TyDecoder> Decodable<__D> for Safety

fn decode(__decoder: &mut __D) -> Self

impl<__E: TyEncoder> Encodable<__E> for Safety

fn encode(&self, __encoder: &mut __E)

impl<'__ctx> HashStable<StableHashingContext<'__ctx>> for Safety

fn hash_stable( &self, __hcx: &mut StableHashingContext<'__ctx>, __hasher: &mut StableHasher )

impl PartialEq for Safety

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

impl Copy for Safety

impl Eq for Safety

impl StructuralPartialEq for Safety

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.
