Trait font_types::Scalar

pub trait Scalar {
    type Raw: Copy + AsRef<[u8]>;

    // Required methods
    fn from_raw(raw: Self::Raw) -> Self;
    fn to_raw(self) -> Self::Raw;
}

A trait for font scalars.

This is an internal trait for encoding and decoding big-endian bytes.

You do not need to implement this trait directly; it is an implemention detail of the BigEndian wrapper.

Required Associated Types

type Raw: Copy + AsRef<[u8]>

The raw byte representation of this type.

Required Methods

fn from_raw(raw: Self::Raw) -> Self

Create an instance of this type from raw big-endian bytes

fn to_raw(self) -> Self::Raw

Encode this type as raw big-endian bytes
