The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

"smallnum" crate: compile-time size optimization for numeric primitives
Thus, this crate provides a macro to automatically determine the smallest integer type that can "fit" a constant max. When the size of a backing collection is known at compile-time (e.g. when using crates like `smallvec` for `!#[no_std]` development), this compile-time optimization can help save precious bytes - potentially for every node in an index-based structure (see README examples). Currently supports signed and unsigned numbers, but I’d love help with floating point support if anyone has ideas (though I don't know what a realistic usecase would be :P).

"smallnum" crate: compile-time size optimization for numeric primitives
It looks like all these macros do is return a type and nothing else? Why can't this just be done by hand? I've done something similar for the macro for deranged, but that's for integers with a known and enforced range.
What are some alternatives?
When comparing smallnum and deranged you can also consider the following projects:
derive_more - Some more derive(Trait) options
rfcs - RFCs for changes to Rust
rust-bitfield - This crate provides macros to generate bitfield-like struct.
rust-derive-builder - derive builder implementation for rust structs
rust-cpp - Embed C++ directly inside your rust code!
