minimum and maximum numbers for various integer types

Rust provides various integer types with different sizes and ranges. Here are the minimum and maximum numbers for some of the integer types in Rust:

• i8: Minimum value is -128 and maximum value is 127.
• u8: Minimum value is 0 and maximum value is 255.
• i16: Minimum value is -32768 and maximum value is 32767.
• u16: Minimum value is 0 and maximum value is 65535.
• i32: Minimum value is -2147483648 and maximum value is 2147483647.
• u32: Minimum value is 0 and maximum value is 4294967295.
• i64: Minimum value is -9223372036854775808 and maximum value is 9223372036854775807.
• u64: Minimum value is 0 and maximum value is 18446744073709551615.
• i128: Minimum value is -170141183460469231731687303715884105728 and maximum value is 170141183460469231731687303715884105727.
• u128: Minimum value is 0 and maximum value is 340282366920938463463374607431768211455.

Please note that Rust also provides other integer types such as isize and usize which depend on the platform's word size. The ranges for these types vary depending on the platform.
