Constant MAX 

pub const MAX: i32 = i32::MAX; // 2_147_483_647i32

👎Deprecating in a future version: replaced by the MAX associated constant on this type

The largest value that can be represented by this integer type. Use i32::MAX instead.

Examples

// deprecated way
let max = std::i32::MAX;

// intended way
let max = i32::MAX;
