Expand description
An owned smart pointer.
Fields§
§ptr: Box<T>
Implementations§
source§impl<T: 'static> P<T>
impl<T: 'static> P<T>
sourcepub fn and_then<U, F>(self, f: F) -> Uwhere
F: FnOnce(T) -> U,
pub fn and_then<U, F>(self, f: F) -> Uwhere
F: FnOnce(T) -> U,
Move out of the pointer.
Intended for chaining transformations not covered by map
.
sourcepub fn into_inner(self) -> T
pub fn into_inner(self) -> T
Equivalent to and_then(|x| x)
.

This is
true
if this HasAttrs
might support ‘custom’ (proc-macro) inner
attributes. Attributes like #![cfg]
and #![cfg_attr]
are not
considered ‘custom’ attributes. Read morefn attrs(&self) -> &[Attribute]

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.
