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 unwrap(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>.

impl<T> P<[T]>

pub fn new() -> P<[T]>

pub fn from_vec(v: Vec<T>) -> P<[T]>

pub fn into_vec(self) -> Vec<T>
