Struct marker_api::ast::BindingArg

#[repr(C)]
pub struct BindingArg<'ast> { /* private fields */ }

A generic bound in form <identifier=type>. For example, Item=i32 would be the generic binding here:

let _baz: &dyn Iterator<Item=i32> = todo!();
//                      ^^^^^^^^

The corresponding instance would provide the name (Item), the defined type (i32) and potentially the Span if this bound originates from source code.

See paths in expressions for more information.

Implementations

impl<'ast> BindingArg<'ast>

pub fn ident(&self) -> &str

The name of the identifier used in the binding. For example:

let _baz: &dyn Iterator<Item=i32> = todo!();
//                      ^^^^

Would return Item as the identifier.

pub fn ty(&self) -> TyKind<'ast>

The type that the identifier is set to. For example:

let _baz: &dyn Iterator<Item=i32> = todo!();
//                           ^^^

Would return i32 as the type.

pub fn span(&self) -> &Span<'ast>

The Span of the binding.
