Enum Type

    Utf8String,

Represents primitive types of data that can be stored in a typedstream

These type encodings are partially documented here by Apple.

Variants

Utf8String

Encoded string data, usually embedded in an object. Denoted by:

Hex	UTF-8
0x28	+

EmbeddedData

Encoded bytes that can be parsed again as data. Denoted by:

Hex	UTF-8
0x2A	*

Object

An instance of a class, usually with data. Denoted by:

Hex	UTF-8
0x40	@

SignedInt

An i8, i16, or i32. Denoted by:

Hex	UTF-8
0x63	c
0x69	i
0x6c	l
0x71	q
0x73	s

The width is determined by the prefix: i8 has none, i16 has 0x81, and i32 has 0x82.

UnsignedInt

A u8, u16, or u32. Denoted by:

Hex	UTF-8
0x43	C
0x49	I
0x4c	L
0x51	Q
0x53	S

The width is determined by the prefix: u8 has none, u16 has 0x81, and u32 has 0x82.

Float

An f32. Denoted by:

Hex	UTF-8
0x66	f

Double

An f64. Denoted by:

Hex	UTF-8
0x64	d

String(String)

Some text we can reuse later, i.e. a class name.

Array(usize)

An array containing some data of a given length. Denoted by braced digits: [123].

Unknown(u8)

Data for which we do not know the type, likely for something this parser does not implement.

Trait Implementations

impl Clone for Type

fn clone(&self) -> Type

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Type

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

Formats the value using the given formatter.

impl PartialEq for Type

fn eq(&self, other: &Type) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
