Function chain_lib::calculator::try_sub

pub fn try_sub(left: u128, right: u128) -> Option<u128>

The function try_sub in Rust attempts to subtract two u128 values and returns the result if it is greater than the second value, otherwise it returns None.

Arguments:

• left: The left parameter represents the value from which you want to subtract another value.
• right: The right parameter is the value that will be subtracted from the left parameter in the try_sub function.

Returns:

The function try_sub returns an Option<u128>. It returns None if the left value is less than the right value. If the subtraction result is greater than the right value, it returns Some(sub_value), where sub_value is the result of the subtraction. Otherwise, it returns None.
