Struct ValidatedRegionLayout 

pub struct ValidatedRegionLayout { /* private fields */ }

Owned metadata and checked ranges copied from one validated mapping.

This type never retains or returns a slice into cross-process storage.

Implementations

impl ValidatedRegionLayout

pub fn matches_topology(&self, topology: &RegionSetLayout) -> bool

Returns whether this validation belongs to an exact composed topology.

pub unsafe fn validate( bytes: &[u8], expected: ValidationExpectations, topology: &RegionSetLayout, ) -> Result<Self, LayoutError>

Validates a mapping while it is quiescent and before peer mutation begins.

Safety

No process may mutate bytes for the duration of this call. The caller mapping must be the exact future capability range.

pub const fn role(&self) -> RoleId

Returns the validated role.

pub const fn generation(&self) -> u64

Returns the validated generation.

pub const fn mapping_size(&self) -> usize

Returns the exact validated native capability size, including zero padding.

pub fn slot_range(&self, slot: u32) -> Result<Range<usize>, LayoutError>

Returns a checked complete slot range without granting memory access.

pub fn acknowledgement_range( &self, index: u32, ) -> Result<Range<usize>, LayoutError>

Returns a checked acknowledgement cell range without granting access.
