Struct rustc_ast::ptr::P

source ·
pub struct P<T: ?Sized> {
    ptr: Box<T>,
}
Expand description

An owned smart pointer.

Fields

ptr: Box<T>

Implementations

Move out of the pointer. Intended for chaining transformations not covered by map.

Equivalent to and_then(|x| x).

Produce a new P<T> from self without reallocating.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
