Struct devise::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 Clone for PredicateType

pub 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

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

Formats the value using the given formatter.

impl From<PredicateType> for WherePredicate

pub fn from(e: PredicateType) -> WherePredicate

Performs the conversion.

impl Hash for PredicateType

pub 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, 

Feeds a slice of this type into the given Hasher.

impl PartialEq<PredicateType> for PredicateType

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

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

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

This method tests for !=.

impl ToTokens for PredicateType

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

Write self to the given TokenStream.

fn into_token_stream(self) -> TokenStream
