Implementations

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,

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

pub fn filter_map<F>(self, f: F) -> Option<P<T>>

where F: FnOnce(T) -> Option<T>,

Optionally produce a new P<T> from self without reallocating.

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>

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.
