Rust data type
There are several basic data types in the Rust language.
Integer type
Integer type is referred to as integer type, which can be divided into the following categories according to bit length and sign or not:
Bit length |
Signed |
Unsigned |
|---|---|---|
8-bit |
I8 |
U8 |
16-bit |
I16 |
U16 |
32-bit |
I32 |
U32 |
64-bit |
I64 |
U64 |
128-bit |
I128 |
U128 |
Arch |
Isize |
Usize |
Two types of integers isize and usize are used to measure data size, and their bit length depends on the target platform on which they are running, and processors with 32-bit architecture will use 32-bit length integers.
Integers are expressed in the following ways:
Binary system |
Example |
|---|---|
Decimal system |
98_222 |
hexadecimal |
0xff |
Octal system |
0o77 |
Binary system |
0b1111_0000 |
Bytes (can only represent type U8) |
