Implementations§

Source§

impl ICU4XReorderedIndexMap

Source

pub fn as_slice<'a>(&'a self) -> &'a [usize]

Get this as a slice/array of indices

Source

pub fn len(&self) -> usize

The length of this map

Source

pub fn is_empty(&self) -> bool

Whether this map is empty

Source

pub fn get(&self, index: usize) -> usize

Get element at index. Returns 0 when out of bounds (note that 0 is also a valid in-bounds value, please use len() to avoid out-of-bounds)
