Expand description

Information extracted from a trait method for code generation.

Collects everything needed to generate vtable shims, view methods, and extra trait bounds for a single method in a #[miniextendr] trait.

Fields§

§name: Ident

Method name (Rust identifier).

§has_self: bool

Whether the method has a self receiver (instance method). False for static/associated methods.

§is_mut: bool

Whether receiver is &mut self (vs &self). Only meaningful if has_self is true.

§param_types: Vec<Type>

Parameter types (excluding the self receiver).

§param_names: Vec<Ident>

Parameter names (excluding the self receiver). Uses arg{i} for unnamed patterns.

§return_type: Option<Type>

Return type. None when the method returns () (unit type or no return annotation).

§skip: bool

Whether method is marked #[miniextendr(skip)], excluding it from codegen.

§r_name: Option<String>

Override the R-facing method name (from #[miniextendr(r_name = "...")]). When set, R wrappers and TPIE metadata use this name instead of the Rust ident.

impl<T> SizeHint for T
where T: ?Sized,

Source §

default fn lower_bound(&self) -> usize

🔬This is a nightly-only experimental API. (core_io_internals)

Returns a lower bound on the number of elements this container-like item contains. For example, an array [u8; 12] could return any value between 0 and 12 inclusively as a correct implementation. Read more

default fn upper_bound(&self) -> Option<usize>

🔬This is a nightly-only experimental API. (core_io_internals)

Returns an upper bound on the number of elements this container-like item contains if it can be determined, otherwise None. Read more

Source §

final fn size_hint(&self) -> (usize, Option<usize>)

🔬This is a nightly-only experimental API. (core_io_internals)

Returns an estimate for the number of elements this container like type contains. Read more
