Struct glsl::syntax::NonEmpty

pub struct NonEmpty<T>(pub Vec<T>);

A non-empty Vec. It has at least one element.

Implementations

impl<T> NonEmpty<T>

pub fn from_non_empty_iter<I>(iter: I) -> Option<Self> where
    I: IntoIterator<Item = T>, 

Construct a non-empty from an iterator.

Errors

None if the iterator yields no value.

pub fn push(&mut self, item: T)

Move a new item at the end of the non-empty.

pub fn pop(&mut self) -> Option<T>

Move out the last element of the non-empty.

Errors

This function returns None if called on a non-empty that contains a single element.

Trait Implementations

impl<T: Clone> Clone for NonEmpty<T>

fn clone(&self) -> NonEmpty<T>

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug> Debug for NonEmpty<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Extend<T> for NonEmpty<T>

fn extend<I>(&mut self, iter: I) where
    I: IntoIterator<Item = T>, 

Extends a collection with the contents of an iterator.

pub fn extend_one(&mut self, item: A)

🔬 This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

pub fn extend_reserve(&mut self, additional: usize)

🔬 This is a nightly-only experimental API. (extend_one)

Reserves capacity in a collection for the given number of additional elements.
