A meta-crate for Rust that re-exports a collection of numeric types and traits, including big integers, rationals, complex numbers, and generic integer traits. It supports no_std environments and generic programming over numeric properties.

Use cases

• do arbitrary-precision integer arithmetic in Rust
• work with rational numbers and fractions
• use complex numbers in numeric code
• write generic functions over integer types
• use numeric traits in no_std embedded Rust

When to choose

• you need bignum, rational, or complex number support in Rust
• you want generic numeric trait abstractions like Integer or Num
• you need numeric libraries that work without the standard library

When to avoid

• you only need one sub-crate and want to minimize dependencies
• you need floating-point linear algebra or matrix math
• you are not programming in Rust
