Enum GenericBound

pub enum GenericBound {
    TraitBound {
        trait_: Path,
        generic_params: Vec<GenericParamDef>,
        modifier: TraitBoundModifier,
    },
    Outlives(String),
    Use(Vec<String>),
}

Either a trait bound or a lifetime bound.

Variants

TraitBound

A trait bound.

Fields

trait_: Path

The full path to the trait.

generic_params: Vec<GenericParamDef>

Used for Higher-Rank Trait Bounds (HRTBs)

where F: for<'a, 'b> Fn(&'a u8, &'b u8)
         ^^^^^^^^^^^
         |
         this part

modifier: TraitBoundModifier

The context for which a trait is supposed to be used, e.g. `const

Outlives(String)

A lifetime bound, e.g.

fn f<'a, T>(x: &'a str, y: &T) where T: 'a {}
//                                     ^^^

Use(Vec<String>)

use<'a, T> precise-capturing bound syntax

Trait Implementations

impl Clone for GenericBound

fn clone(&self) -> GenericBound

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GenericBound

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GenericBound

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for GenericBound

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 PartialEq for GenericBound

fn eq(&self, other: &GenericBound) -> 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 Serialize for GenericBound

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for GenericBound

impl StructuralPartialEq for GenericBound

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.
