Trait read_fonts::FontReadWithArgs

pub trait FontReadWithArgs<'a>: Sized + ReadArgs {
    // Required method
    fn read_with_args(
        data: FontData<'a>,
        args: &Self::Args
    ) -> Result<Self, ReadError>;
}

A trait for types that require external data in order to be constructed.

You should not need to use this directly; it is intended to be used from generated code. Any type that requires external arguments also has a custom read constructor where you can pass those arguments like normal.

Required Methods

fn read_with_args( data: FontData<'a>, args: &Self::Args ) -> Result<Self, ReadError>

read an item, using the provided args.

If successful, returns a new item of this type, and the number of bytes used to construct it.

If a type requires multiple arguments, they will be passed as a tuple.

Object Safety

This trait is not object safe.
