Backends

This crate has support for two different field arithmetic backends which can be selected using cfg(bp384_backend), e.g. to select the bigint backend:

$ RUSTFLAGS='--cfg bp384_backend="bigint"' cargo test

Or it can be set through .cargo/config:

[build]
rustflags = ['--cfg', 'bp384_backend="bigint"']

The available backends are:

• bigint: experimental backend provided by crypto-bigint. May offer better performance in some cases along with smaller code size, but might also have bugs.
• fiat (default): formally verified implementation synthesized by fiat-crypto which should be correct for all inputs (though there’s a possibility of bugs in the code which glues to it)
