Cargo Features

[dependencies]
lexical-util = { version = "1.0.6", default-features = false, features = ["std", "power-of-two", "radix", "format", "write-integers", "write-floats", "parse-integers", "parse-floats", "compact", "f16", "lint", "write", "parse", "integers", "floats", "f128"] }

FEATURES
--------
In order to improve compile times, we have separate support for each numeric conversion. Since these features are additive,
if more features are added, separate crates can add support for more features without requiring re-compilation of lexical.

default = std

The std feature is set by default whenever lexical-util is added without default-features = false somewhere in the dependency tree.

std default

Use the standard library.
