Macros for changing arithmetic modes (wrapping / saturating / checked etc)

Provides checked!, panicking!, wrapping! and saturating! macros to change how arithmetic overflows are handled.

This crate currently not published on crates.io

Example

use arithmetic_mode::wrapping;

wrapping! { 1_i32 + 2_i32 - 3_i32 };

Supported operations:

• Add +
• Sub -
• Mul *
• Div /
• Shl << (except saturating, due to rust-lang/libs-team#230)
• Shr >> (except saturating, due to rust-lang/libs-team#230)

Known issues

• For most operations, constraining the numeric literals are required (e.g. 2_i32 instead of 2), due to rust-lang/rust#24124.
