Literals
Integer Literals
Integer literals may use decimal, hexadecimal 0x, binary 0b, or octal 0o bases.
42 // decimal
0xFF // hexadecimal
0o77 // octal
0b10101010 // binary
There are suffixes i8, i16, i32, i64, i128, i256, i512, u8, u16, u32, u64, u128, u256, u512 to specify integer types.
-16i8 // int8
-16i16 // int16
-16i32 // int32
-16i64 // int64
-16i128 // int128
-16i256 // int256
-16i512 // int512
255u8 // uint8
255u16 // uint16
255u32 // uint32
255u64 // uint64
255u128 // uint128
255u256 // uint256
255u512 // uint512
255 // int positive
-255 // int negative
255i // int
255u // uint
Prefixes and suffixes can be combined in literals.
0b10001111i32 // int32 in binary format
0o70500u64 // uint64 in octal format
0xFFu8 // uint8 in hexadecimal format
Floating-Point Literals
3.1415 // float
3.1415f32 // float32
3.1415f64 // float64
1.0e9 // float scientific format

Character Literals
A character literal contains exactly one character (or one escape sequence) enclosed in single quotes. Its default type is char:
'A'
'∀'
'🍏'
'🍉'
'😁'
'\n'
'\\'
'a' // char
c8'b' // char8
c16'c' // char16
c32'd' // char32
String Literals
String literals are slices of type Slice<char8> enclosed in double quotes. Standard escape sequences are supported:
"Hello, World!"
"Line one\nLine two"
"Tab\there"
"Quote: \""
"Backslash: \\"
| Escape | Meaning |
|---|---|
\n | Newline |
\t | Horizontal tab |
\r | Carriage return |
\0 | Null byte |
\\ | Backslash |
\' | Single quote |
\" | Double quote |
\u{XXXX} | Unicode code point |
