# [−][src]Module num_traits::ops::checked

## Traits

CheckedAdd | Performs addition that returns `None` instead of wrapping around on overflow.
CheckedDiv | Performs division that returns `None` instead of panicking on division by zero and instead of wrapping around on underflow and overflow.
CheckedMul | Performs multiplication that returns `None` instead of wrapping around on underflow or overflow.
CheckedNeg | Performs negation that returns `None` if the result can't be represented.
CheckedRem | Performs an integral remainder that returns `None` instead of panicking on division by zero and instead of wrapping around on underflow and overflow.
CheckedShl | Performs a left shift that returns `None` on shifts larger than the type width.
CheckedShr | Performs a right shift that returns `None` on shifts larger than the type width.
CheckedSub | Performs subtraction that returns `None` instead of wrapping around on underflow.

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
