Struct syn::PredicateType

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

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

This type is available if Syn is built with the "derive" or "full" feature.

Fields

lifetimes: Option<BoundLifetimes>

Any lifetimes from a for binding

bounded_ty: Type

The type being bounded

colon_token: Colon

bounds: Punctuated<TypeParamBound, Add>

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

Trait Implementations

impl ToTokens for PredicateType

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

Write self to the given TokenStream.

fn into_token_stream(self) -> TokenStream

Convert self directly into a TokenStream object.

impl Debug for PredicateType

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

Formats the value using the given formatter.

impl Eq for PredicateType

impl PartialEq for PredicateType

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Hash for PredicateType

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,

Feeds a slice of this type into the given [Hasher].

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 From<PredicateType> for WherePredicate

fn from(e: PredicateType) -> WherePredicate

Performs the conversion.
