Struct Decoder

pub struct Decoder<'a> {
    pub bytecode: &'a [u8],
    pub pc: usize,
}

Decodes instructions from TrueType bytecode.

Fields

bytecode: &'a [u8]

The bytecode for the program.

pc: usize

The “program counter” or current offset into the bytecode.

Implementations

impl<'a> Decoder<'a>

pub fn new(bytecode: &'a [u8], pc: usize) -> Self

Creates a new decoder for the given bytecode and program counter.

pub fn decode(&mut self) -> Option<Result<Instruction<'a>, DecodeError>>

Decodes the next instruction.

Returns None at the end of the bytecode stream.

Trait Implementations

impl<'a> Clone for Decoder<'a>

fn clone(&self) -> Decoder<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
