Variants

Unused

unsafe block contains no unsafe operations

unnecessary `unsafe` block

InUnsafeBlock(HirId)

unsafe block nested under another (used) unsafe block

… because it's nested under this `unsafe` block

Trait Implementations

impl Clone for UnusedUnsafe

fn clone(&self) -> UnusedUnsafe

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UnusedUnsafe

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

Formats the value using the given formatter.

impl<'tcx, __D: TyDecoder<I = TyCtxt<'tcx>>> Decodable<__D> for UnusedUnsafe

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

impl<'tcx, __E: TyEncoder<I = TyCtxt<'tcx>>> Encodable<__E> for UnusedUnsafe

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

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

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

impl PartialEq<UnusedUnsafe> for UnusedUnsafe

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