Struct syn::PredicateType

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

This is supported on crate features full or derive only.

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

This type is available only 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

This is supported on crate feature clone-impls only.

pub fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PredicateType

This is supported on crate feature extra-traits only.

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

Formats the value using the given formatter.

impl Eq for PredicateType

This is supported on crate feature extra-traits only.

impl From<PredicateType> for WherePredicate

pub fn from(e: PredicateType) -> WherePredicate

Performs the conversion.

impl Hash for PredicateType

This is supported on crate feature extra-traits only.

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

Feeds this value into the given Hasher.

pub 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

This is supported on crate feature extra-traits only.

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

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

#[must_use]pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl ToTokens for PredicateType

This is supported on crate feature printing only.

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

Write self to the given TokenStream.

pub fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

pub fn into_token_stream(self) -> TokenStream

Convert self directly into a TokenStream object.
