Trait 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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
