Enum rustc_ast::ast::Safety

pub enum Safety {
    Unsafe(Span),
    Safe(Span),
    Default,
}

Safety of items.

Variants

Unsafe(Span)

unsafe an item is explicitly marked as unsafe.

Safe(Span)

safe an item is explicitly marked as safe.

Default

Default means no value was provided, it will take a default value given the context in which is used.

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: SpanDecoder> Decodable<__D> for Safety

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

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

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

impl Hash for Safety

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<__CTX> HashStable<__CTX> for Safety

where __CTX: HashStableContext,

fn hash_stable(&self, __hcx: &mut __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.
