Struct read_fonts::array::VarLenArray

source · 
pub struct VarLenArray<'a, T> { /* private fields */ }
Expand description

An array of items of non-uniform length.

Random access into this array cannot be especially efficient, since it requires a linear scan.

Implementations§

source§

impl<'a, T: FontRead<'a> + VarSize> VarLenArray<'a, T>

source

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

Return the item at the provided index.

This performs a linear search.

source

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

Return an iterator over this array’s items.
