dmidecode

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.

# Cargo.toml
[dependencies]
dmidecode = "0.9"

Example

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.

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.
