Struct pulley_interpreter::decode::SafeBytecodeStream

pub struct SafeBytecodeStream<'a> { /* private fields */ }

Available on crate feature decode only.

A 100% safe implementation of a bytecode stream.

This is a thin wrapper around an index into a &[u8].

Implementations

impl<'a> SafeBytecodeStream<'a>

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

Create a new SafeBytecodeStream from the given slice and with an initial position pointing at the start of the slice.

pub fn position(&self) -> usize

Get this stream’s current position within its underlying slice.

pub fn as_slice(&self) -> &[u8]

Get this stream’s underlying bytecode slice.

Trait Implementations

impl BytecodeStream for SafeBytecodeStream<'_>

type Error = DecodingError

The type of error that this bytecode stream produces on invalid operations.

fn read<const N: usize>(&mut self) -> Result<[u8; N], Self::Error>

Read N bytes from this bytecode stream, advancing the stream’s position at the same time.

fn unexpected_eof(&self) -> Self::Error

Create an “unexpected end-of-stream” error at the current position.

fn invalid_opcode(&self, code: u8) -> Self::Error

Create an “invalid opcode” error at the current position.

fn invalid_extended_opcode(&self, code: u16) -> Self::Error

Create an “invalid extended opcode” error at the current position.

fn invalid_reg(&self, reg: u8) -> Self::Error

Create an “invalid register” error at the current position.

impl<'a> Clone for SafeBytecodeStream<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for SafeBytecodeStream<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
