Rhai takes care to pull in as few dependencies as possible in order to avoid bloat when using the library.
Crate Description Why use it?
smallvecVec variant that stores a number of items inlinemost functions have very few parameters, and avoiding allocations result in significant performance improvement num-traitsnumeric traits for use with macros defining arithmetic functions and operators ahashfast hashing for data not cryptographically secure, thus faster than standard Rust hashing; Rhai does a lot of hashing so this matters bitflagsbit fields store flags in AST smartstringString variant that stores short strings inlinemost strings in scripts (e.g. keywords, properties, symbols, variables, function names etc.) are short, and avoiding allocations result in significant performance improvement
