Trait acpi::AcpiTable

pub unsafe trait AcpiTable {
    const SIGNATURE: Signature;

    // Required method
    fn header(&self) -> &SdtHeader;

    // Provided method
    fn validate(&self) -> AcpiResult<()> { ... }
}

All types representing ACPI tables should implement this trait.

Safety

The table’s memory is naively interpreted, so you must be careful in providing a type that correctly represents the table’s structure. Regardless of the provided type’s size, the region mapped will be the size specified in the SDT’s header. Providing a table impl that is larger than this, may lead to page-faults, aliasing references, or derefencing uninitialized memory (the latter two being UB). This isn’t forbidden, however, because some tables rely on the impl being larger than a provided SDT in some versions of ACPI (the ExtendedField type will be useful if you need to do this. See our Fadt type for an example of this).
