Struct gvariant::NonFixedWidthArray

#[repr(transparent)]
pub struct NonFixedWidthArray<T: Cast + ?Sized> { /* private fields */ }

Type with same representation as GVariant “aX” type where X is any non-fixed size type

This is similar to a slice, but for non-fixed width types, and implements many of the same methods. Items can be retrieved by indexing or iterated over.

For fixed-width types a standard rust slice is used.

Implementations

impl<T: Cast + ?Sized> NonFixedWidthArray<T>

pub fn len(&self) -> usize

Returns the number of elements in the array.

pub fn is_empty(&self) -> bool

Returns true if the array has a length of 0.

pub fn iter(&self) -> NonFixedWidthArrayIterator<'_, T>

Returns an iterator over the array.

pub fn first(&self) -> Option<&T>

Returns the first element of the array, or None if it is empty.

pub fn last(&self) -> Option<&T>

Returns the last element of the array, or None if it is empty.
