Cargo Features
[dependencies]
lexical-util = { version = "1.0.3", 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 wheneverlexical-util
is added without
somewhere in the dependency tree.default-features = false - std default
-
Use the standard library.
- power-of-two radix?
-
Add support for numerical conversions with power-of-two strings.
