Struct PredicateType

pub struct PredicateType {
    pub lifetimes: Option<BoundLifetimes>,
    pub bounded_ty: Type,
    pub colon_token: Colon,
    pub bounds: Punctuated<TypeParamBound, Plus>,
}

A type predicate in a where clause: for<'c> Foo<'c>: Trait<'c>.

Fields

lifetimes: Option<BoundLifetimes>

Any lifetimes from a for binding

bounded_ty: Type

The type being bounded

colon_token: Colon

bounds: Punctuated<TypeParamBound, Plus>

Trait and lifetime bounds (Clone+Send+'static)

Trait Implementations

impl Clone for PredicateType

fn clone(&self) -> PredicateType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PredicateType

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

Formats the value using the given formatter.

impl From<PredicateType> for WherePredicate

fn from(e: PredicateType) -> WherePredicate

Converts to this type from the input type.

impl Hash for PredicateType

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

where H: Hasher,

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 PredicateType

fn eq(&self, other: &PredicateType) -> 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 ToTokens for PredicateType

fn to_tokens(&self, tokens: &mut TokenStream)

Write self to the given TokenStream.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,

Convert self directly into a TokenStream object.
