Struct lazy_seq::Lazy

pub struct Lazy<T> { /* private fields */ }

Stores an operation which can be evaluated when required.

Implementations

impl<T> Lazy<T>

pub fn new<F: FnOnce() -> T + 'static>(f: F) -> Lazy<T>

Constructs a new Lazy<T> from a closure implementing FnOnce() -> T.

pub fn force(&mut self)

Forces evaluation of the underlying function.

pub fn into_inner(self) -> T

Forces evaluation of the underlying function and returns the inside value, consuming the Lazy<T>.

pub fn as_ref(&mut self) -> &T

Returns an immutable reference to the result of the function.

Trait Implementations

impl<T> AsMut<T> for Lazy<T>

fn as_mut(&mut self) -> &mut T

Returns a mutable reference to the result of the function.

impl<T> Default for Lazy<T> where
    T: Default, 

fn default() -> Self

Returns the “default value” for a type.
