This package provides a runtime equivalent of the Rust format! macro. It allows formatting strings like the format! macro, with the formatting string and the arguments provided at runtime. This crate supports all the formatting features of the format! macro, except for the fill character.

This package provides a string allocator for allocating many write-once strings. This library is primarily useful for parsing where you need to repeatedly build many strings, use them, and then throw them away. Instead of allocating many independent strings, this library will put them all in the same buffer.

This crate provides #[test_case] procedural macro attribute that generates multiple parametrized tests using one body with different input parameters. A test is generated for each data set passed in test_case attribute. Under the hood, all test cases that share same body are grouped into mod, giving clear and readable test results.

This package provides a key-value dictionary, using copy-on-write and B trees. It features:

• ACID semantics.

• B trees with copy-on-write.

• Support for referential transparency: databases can be cloned in time O(log n) (where n is the size of the database). This was the original motivation for writing this library.

The Arbitrary crate lets you construct arbitrary instance of a type.

This crate is primarily intended to be combined with a fuzzer like libFuzzer and cargo-fuzz or AFL, and to help you turn the raw, untyped byte buffers that they produce into well-typed, valid, structured values. This allows you to combine structure-aware test case generation with coverage-guided, mutation-based fuzzers.
