Webb24 juli 2024 · The default integer type in Rust is i32. Signed integer types in Rust start with i and it has 8, 16, 32, 64, and 128-bit. The minimum and maximum values are from - (2ⁿ⁻¹) to 2ⁿ⁻¹-1. The -1 in the n-1 is the sign bit (positive or negative), which we cover in the next section. For example i8 has - (2⁷) to 2⁷-1, which is -128 to 127.
