i2c-scanner for Linux written in Rust

Detects i2c addresses using roughly same way as i2cdetect.

Checks i2c database to display possible matching devices models by their found i2c addresses.

(The code was generated based on data in https://i2cdevices.org database)

Building

cd rust-i2c-scan
cargo build

Sample output
