pub struct P<T: ?Sized> { /* fields omitted */ }
rustc_private
)An owned smart pointer.
Methods
impl<T: 'static> P<T>
[src]
fn and_then<U, F>(self, f: F) -> U where F: FnOnce(T) -> U
rustc_private
)Move out of the pointer.
Intended for chaining transformations not covered by map
.
fn unwrap(self) -> T
rustc_private
)Equivalent to and_then(|x| x)
fn map<F>(self, f: F) -> P<T> where F: FnOnce(T) -> T
rustc_private
)Transform the inner value, consuming self
and producing a new P<T>
.
