pub enum Error {
    InvalidGuestRegion,
    MmapRegion(MmapRegionError),
    NoMemoryRegion,
    MemoryRegionOverlap,
    UnsortedMemoryRegions,
}

Errors that can occur when creating a memory map.

Variants

InvalidGuestRegion

Adding the guest base address to the length of the underlying mapping resulted in an overflow.

MmapRegion(MmapRegionError)

Error creating a MmapRegion object.

NoMemoryRegion

No memory region found.

MemoryRegionOverlap

Some of the memory regions intersect with each other.

UnsortedMemoryRegions

The provided memory regions haven’t been sorted.

Trait Implementations

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide(&'a self, req: &mut Demand<'a>)

🔬 This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.
