Builtin

Core Odin procs that are available to use without any imports.

Platform constants

ODIN_OS

Current compiler platform os. "windows" "darwin" (MacOS) "linux"

ODIN_ARCH

ODIN_ENDIAN

The endianness of the target system. "little" or "big".

ODIN_VENDOR

ODIN_VERSION

ODIN_ROOT

ODIN_DEBUG

A boolean indicating whether debug information was requested on the command line. (-debug was passed.)

Types

byte

Alias for u8.

Useful if you want to indicate that the u8 is being used as data instead of a number.

Boolean

bool

8-bit boolean type.

b8

8-bit boolean type.

b16

16-bit boolean type.

b32

32-bit boolean type.

b64

64-bit boolean type.

Integer

i8

8-bit signed integer.

u8

8-bit unsigned integer.

i16

16-bit signed integer.

u16

16-bit unsigned integer.

i32

32-bit signed integer.

u32

32-bit unsigned integer.

i64

64-bit signed integer.

u64

64-bit unsigned integer.

i128

128-bit signed integer.

u128

128-bit unsigned integer.

rune

32-bit unicode codepoint.

Floating Point

f32

32-bit floating point number.

f64

64-bit floating point number.

Complex

complex32

complex64

complex128

quaternion128

quaternion256

int

Word-sized signed integer.

Not to be confused with C's int.

uint

Word-sized unsigned integer.

Not to be confused with C's unsigned int.

uintptr

rawptr

Pointer to memory address. Same function as void * in c. Prefer ^T where possible in odin.

Any other pointer type will implicitly cast to rawptr.

string

UTF-8 encoded string.

cstring

C style string with null terminator \0

any

Contains a pointer and a typeid describing the type of the thing it is pointing to.

typeid

A unique ID for a type.
