Struct ArrayOfNullableOffsets

source
pub struct ArrayOfNullableOffsets<'a, T: ReadArgs, O: Scalar = Offset16> { /* private fields */ }
Expand description

An array of nullable offsets that can be resolved on access.

This is identical to ArrayOfOffsets, except that each offset is allowed to be null.

Implementations§

source§

impl<'a, T, O> ArrayOfNullableOffsets<'a, T, O>
where O: Scalar + Offset, T: ReadArgs + FontReadWithArgs<'a>, T::Args: Copy + 'static,

source

pub fn len(&self) -> usize

The number of offsets in the array

source

pub fn is_empty(&self) -> bool

true if the array is empty

source

pub fn get(&self, idx: usize) -> Option<Result<T, ReadError>>

Resolve the offset at the provided index.

This will return None only if the offset exists, but is null. if the provided index does not exist, this will return the InvalidCollectionIndex error variant.

source

pub fn iter(&self) -> impl Iterator<Item = Option<Result<T, ReadError>>> + 'a

Iterate over all of the offset targets.

Each offset will be resolved as it is encountered.
