This crate provides types for representing the RSDP (the Root System Descriptor Table; the first ACPI table)
and methods for searching for it on BIOS systems. Importantly, this crate (unlike
acpi, which re-exports the
contents of this crate) does not need
alloc, and so can be used in environments that can’t allocate. This is
specifically meant to be used from bootloaders for finding the RSDP, so it can be passed to the payload. If you
don’t have this requirement, and want to do more than just find the RSDP, you can use
acpi instead of this
To use this crate, you will need to provide an implementation of
AcpiHandler. This is the same handler type
used in the
The first structure found in ACPI. It just tells us where the RSDT is.
