Struct PartialConstStability 

pub struct PartialConstStability {
    pub level: StabilityLevel,
    pub feature: Symbol,
    pub promotable: bool,
}

Excludes const_stable_indirect. This is necessary because when -Zforce-unstable-if-unmarked is set, we need to encode standalone #[rustc_const_stable_indirect] attributes

Fields

level: StabilityLevel

feature: Symbol

promotable: bool

whether the function has a #[rustc_promotable] attribute

Implementations

impl PartialConstStability

pub fn is_const_unstable(&self) -> bool

pub fn is_const_stable(&self) -> bool

Trait Implementations

impl Clone for PartialConstStability

fn clone(&self) -> PartialConstStability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PartialConstStability

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

Formats the value using the given formatter.

impl<__D: SpanDecoder> Decodable<__D> for PartialConstStability

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

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

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

impl Hash for PartialConstStability

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 PartialConstStability

where __CTX: HashStableContext,

fn hash_stable(&self, __hcx: &mut __CTX, __hasher: &mut StableHasher)

impl PartialEq for PartialConstStability

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PrintAttribute for PartialConstStability

fn should_render(&self) -> bool

Whether or not this will render as something meaningful, or if it’s skipped (which will force the containing struct to also skip printing a comma and the field name).

fn print_attribute(&self, __p: &mut Printer)

impl Copy for PartialConstStability

impl Eq for PartialConstStability

impl StructuralPartialEq for PartialConstStability

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.
