I found three crates for decimal numbers handling in Rust (these are used in finances, to prevent rounding errors):

• Decimal - GitHub repository, documentation
• Rust Decimal - GitHub repository, documentation
• Bigdecimal - GitHub repository, documentation

And two for some basic financial mathematics:

• finance-math - documentation (see announcement at this forum)
• finance GitHub repository

And two quant trading libraries:

• trade-rs
• ta crate, see documentation and GitHub repository

And one bank interface library:

• bank crate, see documentation and GitLab repository
