battery

Rust crate providing cross-platform information about batteries.

Gives access to a system independent battery state, capacity, charge and voltage values recalculated as necessary to be returned in mW, mWh or mV units.

Supported platforms

• Linux 2.6.39+
• MacOS (10.10+ probably, needs to be confirmed)
• Windows 7+

API stability

Until 1.0.0 version API might change in any moment, be careful.

Example

This crate acts both as library and as binary executable, so you can install and check it:

1. Install battery crate:

$ cargo install battery

2. Call the installed file:

$ ~/.cargo/bin/battery
