Primitive Types

bool

  • bool .

  • Has a size of 1 byte  ( b8 ). 

bool

  • Other bools: 

    b8 b16 b32 b64

    • "The only world where you would use one of these other bools is if you are making a binding for another language that has different sized bool types."

    • bool  is equivalent to b8 .

nil

  • Types that support nil :

    • rawptr

    • any

    • cstring

    • typeid

    • enum

    • bit_set

    • Slices

    • proc  values

    • Pointers

    • #soa  Pointers

    • Multi-Pointers

    • Dynamic Arrays

    • map

    • union  without the #no_nil  directive

    • #soa  slices

    • #soa  dynamic arrays

rawptr

  • rawptr .

  • All pointers can implicitly convert to rawptr .

integer

  • “natural” register size.

    • Is guaranteed to be greater than or equal to the size of a pointer.

    • When you need an integer value, you should default to using int  unless you have a specific reason to use a sized or unsigned integer type 

    int  
uint

  • Specific sizes: 

    i8 i16 i32 i64 i128
u8 u16 u32 u64 u128

  • Pointer size: 

    uintptr

  • Endian-specific integers: 

    // little endian
i16le i32le i64le i128le u16le u32le u64le u128le 

// big endian
i16be i32be i64be i128be u16be u32be u64be u128be

float

  • No need to use f  in front of the float. 

f16 f32 f64

  • Endian-specific floating point numbers: 

    // little endian
f16le f32le f64le 

// big endian
f16be f32be f64be

rune

  • Signed 32-bit integer.

  • Represents a Unicode code point.

  • Is a distinct type from i32 .
