Struct ttf_parser::LazyArray16

pub struct LazyArray16<'a, T> {
    data: &'a [u8],
    data_type: PhantomData<T>,
}

A slice-like container that converts internal binary data only on access.

Array values are stored in a continuous data chunk.

Fields

data: &'a [u8]

data_type: PhantomData<T>

Implementations

impl LazyArray16<'_, RangeRecord>

pub fn range(&self, glyph: GlyphId) -> Option<RangeRecord>

Returns a RangeRecord for a glyph.

impl<'a, T: FromData> LazyArray16<'a, T>

pub fn new(data: &'a [u8]) -> Self

Creates a new LazyArray.

pub fn get(&self, index: u16) -> Option<T>

Returns a value at index.

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

Returns the last value.

pub fn slice(&self, range: Range<u16>) -> Option<Self>

Returns sub-array.

pub fn len(&self) -> u16
