Cargo Features

accurate = { version = "0.3.1", default-features = false, features = ["fma", "parallel", "clippy", "lint"] }
default = parallel

The parallel feature is set by default whenever accurate is added without default-features = false somewhere in the dependency tree.

parallel default = rayon

Affects dot::DotFolder, dot::DotConsumer, traits::ParallelDotAccumulator, traits::ParallelDotWithAccumulator, sum::SumFolder, sum::SumConsumer, traits::ParallelSumAccumulator, traits::ParallelSumWithAccumulator, util::AddReducer

clippy lint?
lint = clippy
