pub fn checked_sub<T: UnsignedPrimInt>(left: T, right: T) -> Option<T>👎Deprecated:
Use primint :: checked_sub directly.
Expand description
An alias for [primint :: checked_sub].
This is logically a re-export, but a wrapper function is used instead as re-exports can’t currently be deprecated (rust-lang/rust#30827)
This function will be removed in the next semver-breaking release.
