Struct ComputedArray

source
pub struct ComputedArray<'a, T: ReadArgs> { /* private fields */ }
Expand description

An array whose items size is not known at compile time.

This requires the inner type to implement FontReadWithArgs as well as ComputeSize.

At runtime, Args are provided which will be used to compute the size of each item; this size is then used to compute the positions of the items within the underlying data, from which they will be read lazily.
