Struct syntax::ptr::P

pub struct P<T: ?Sized> { /* fields omitted */ }

Methods

impl<T: 'static> P<T>

pub fn and_then<U, F>(self, f: F) -> U where     F: FnOnce(T) -> U,

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

pub fn into_inner(self) -> T

Equivalent to and_then(|x| x)

pub fn map<F>(self, f: F) -> P<T> where     F: FnOnce(T) -> T,

Transform the inner value, consuming self and producing a new P<T>.
