Expand description

Generates an implementation of a binary operate-assign Trait for a scalar type

This macro requires the following arguments:

$type - The Type the binary operate-assign Trait is implemented for
$type_prim - The primitive Rust scalar type that corresponds to $type
$opname - The Trait for which the implementation is generated
$expr - A closure providing the logic for the implementation
$docstring - String to include as the Doc comment for the Trait implementation

Example Usage:

gen_binopassign!(Rint, i32, AddAssign, |lhs: i32, rhs| lhs.checked_add(rhs), "Doc Comment");

The ‘example usage’ implements the following trait definitions:
