Struct TraitClause

pub struct TraitClause {
    pub clause_id: TraitClauseId,
    pub span: Option<Span>,
    pub origin: PredicateOrigin,
    pub trait_: PolyTraitDeclRef,
}

A predicate of the form Type: Trait<Args>.

Fields

clause_id: TraitClauseId

We use this id when solving trait constraints, to be able to refer to specific where clauses when the selected trait actually is linked to a parameter.

span: Option<Span>

origin: PredicateOrigin

Where the predicate was written, relative to the item that requires it.

trait_: PolyTraitDeclRef

The trait that is implemented.

Trait Implementations

impl Clone for TraitClause

fn clone(&self) -> TraitClause

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TraitClause

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TraitClause

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Drive for TraitClause

fn drive<V: Visitor>(&self, visitor: &mut V)

impl DriveMut for TraitClause

fn drive_mut<V: VisitorMut>(&mut self, visitor: &mut V)

impl<C: AstFormatter> FmtWithCtx<C> for TraitClause

fn fmt_with_ctx(&self, ctx: &C) -> String

fn fmt_with_ctx_and_indent(&self, _tab: &str, _ctx: &C) -> String

fn with_ctx<'a>(&'a self, ctx: &'a C) -> impl Display + 'a

Returns a struct that implements Display. This allows the following:

impl PartialEq for TraitClause

fn eq(&self, other: &Self) -> 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 Serialize for TraitClause

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
