Struct WherePredicate

pub struct WherePredicate {
    pub attrs: AttrVec,
    pub kind: WherePredicateKind,
    pub id: NodeId,
    pub span: Span,
    pub is_placeholder: bool,
}

A single predicate in a where-clause.

Fields

attrs: AttrVec

kind: WherePredicateKind

id: NodeId

span: Span

is_placeholder: bool

Trait Implementations

impl Clone for WherePredicate

fn clone(&self) -> WherePredicate

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WherePredicate

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

Formats the value using the given formatter.

impl<__D: SpanDecoder> Decodable<__D> for WherePredicate

fn decode(__decoder: &mut __D) -> Self

impl<__E: SpanEncoder> Encodable<__E> for WherePredicate

fn encode(&self, __encoder: &mut __E)

impl HasAttrs for WherePredicate

const SUPPORTS_CUSTOM_INNER_ATTRS: bool = false

This is true if this HasAttrs might support ‘custom’ (proc-macro) inner attributes. Attributes like #![cfg] and #![cfg_attr] are not considered ‘custom’ attributes.

fn attrs(&self) -> &[Attribute]

fn visit_attrs(&mut self, f: impl FnOnce(&mut AttrVec))

impl HasNodeId for WherePredicate

fn node_id(&self) -> NodeId

fn node_id_mut(&mut self) -> &mut NodeId

impl HasTokens for WherePredicate

fn tokens(&self) -> Option<&LazyAttrTokenStream>

fn tokens_mut(&mut self) -> Option<&mut Option<LazyAttrTokenStream>>

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.
