Enum RegionCapError 

Source 
pub enum RegionCapError {
    NotFound,
    InvalidRegion,
    IncompleteRegion,
    InvalidAddress,
    PermissionDenied,
    OutOfMemory,
    InconsistentState,
}
Expand description

Errors returned by the public memory-region capability layer.

Variants§

§

NotFound

The requested region capability does not exist.

§

InvalidRegion

The requested virtual region cannot be exported.

§

IncompleteRegion

The region is not fully materialized in the effective mapping table.

§

InvalidAddress

The target address or range is invalid.

§

PermissionDenied

The caller lacks sufficient permissions for the requested operation.

§

OutOfMemory

The target address space cannot host the mapping.

§

InconsistentState

Internal ownership state was inconsistent while publishing the region.
