    None,
    Node(Vec<u8>),
    Int(i32),
    String(String),
    S64(u64),
    Struct(Vec<u8>),

    U32(u32),
}

An Enum that holds all values returned by sysctl calls. Extract inner value with if let or match.

Example

let val_enum = sysctl::value("kern.osrevision");

if let sysctl::CtlValue::Int(val) = val_enum {
    println!("Value: {}", val);
}
