Struct TORRegionSpec

pub struct TORRegionSpec { /* private fields */ }

A RISC-V PMP memory region specification, configured in TOR mode.

This type checks that the supplied start and end addresses meet the RISC-V TOR requirements, namely that

• the region’s start address is aligned to a 4-byte boundary
• the region’s end address is aligned to a 4-byte boundary
• the region is at least 4 bytes long

By accepting this type, PMP implementations can rely on these requirements to be verified.

Implementations

impl TORRegionSpec

pub fn new(start: *const u8, end: *const u8) -> Option<Self>

Construct a new TORRegionSpec

This method accepts a start and end address. It returns Some(region) when all constraints specified in the TORRegionSpec’s documentation are satisfied, otherwise None.

pub fn start(&self) -> *const u8

Retrieve the start address of this TORRegionSpec.

pub fn end(&self) -> *const u8

Retrieve the end address of this TORRegionSpec.
