Constant MAX 

pub const MAX: isize = isize::MAX; // 9_223_372_036_854_775_807isize

👎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 isize::MAX instead.

Examples

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

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