When (not) to use this crate
There are many crates that can be used for formatting values into strings. Here are some of the criteria you can use to decide if this crate is the right choice for you:
- Can you specify all the formatting options at compile time? If yes, then
std::fmtis a better option than this crate. If you need to supply the formatting specifiers at runtime, then this crate might be a viable option.
- Are you formatting only numbers? If yes, consider
- Is using Rust nightly an option? If so, consider
- Do you need the ability to implement new formats? If yes, consider
- Do you need
no-stdsupport? If so, you need to use one of the other alternatives.
- Is formatting likely to be a performance bottleneck for you? If so, you should consider one of the other alternatives. At this time, there are no benchmarks to compare the approach in this crate with other crates.
- Is stable API a must-have? If so, you might consider the alternatives. This crate is still not at version 1.0, which means that the API is still not completely stable.
