    pub trait_name: TypeName,
    pub target_type: TypeName,

Expand description

Impl block — implements a trait for a type

impl Queryable<T> for Table<T> {
    method filter(predicate) { /* ... */ }
    method execute() { Ok(self) }
}

Under the hood, compiles identically to an extend block (UFCS desugaring) plus trait validation (all required methods present with correct arities).

Fields§

§trait_name: TypeName

The trait being implemented (e.g., Queryable)

§target_type: TypeName

The type implementing the trait (e.g., Table)

§impl_name: Option<String>

Optional named implementation selector: impl Display for User as JsonDisplay { ... }

§methods: Vec<MethodDef>

Method implementations

§associated_type_bindings: Vec<AssociatedTypeBinding>

Associated type bindings: type Item = number;

§where_clause: Option<Vec<WherePredicate>>

Where clause: where T: Display + Comparable
