A Rust library for parsing raw **SMBIOS/DMI tables**. This crate lets you read and decode system firmware information provided via `/sys/firmware/dmi/tables/` on Linux, or directly from memory dumps.
```toml
# Cargo.toml
[dependencies]
dmidecode = "0.9"
```
## Example
```rust
use dmidecode::Structure;
fn main() -> Result<(), Box<dyn std::error::Error>> {
eprintln!("Collecting DMI Information...");
// Get the SMBIOS header and DMI table from sysfs.
let buf = std::fs::read("/sys/firmware/dmi/tables/smbios_entry_point")?;
let dmi = std::fs::read("/sys/firmware/dmi/tables/DMI")?;
let entry = dmidecode::EntryPoint::search(&buf)?;
for table in entry.structures(&dmi) {
let Ok(table) = table else {
eprintln!("DMI tables contain malformed structure: {table:?}");
continue;
};
match table {
Structure::System(system) => {
// do stuff
}
Structure::BaseBoard(base_board) => {
// do stuff
}
// ...
_ => continue,
}
}
Ok(())
}
```
## No-std support
In no_std mode, almost all of the same API is available and works the same
way. To depend on `dmidecode` in `no_std` mode, disable our default enabled
`std` feature in `Cargo.toml`.
The `std` feature just implements the `Error` trait on error types used by
`dmidecode`.
```toml
[dependencies]
dmidecode = { version = "0.9", default-features = false }
```
## Rust Version Support The minimum supported Rust version is documented in
the Cargo.toml file. This may be bumped in minor releases as necessary.
## License
`dmidecode` is released under the terms of the [MIT](./LICENSE) license.
