Available on crate feature xen and target_family=unix and crate feature backend-mmap only.

Error conditions that may arise when creating a new MmapRegion object.

Variants

InvalidOffsetLength

The specified file offset and length cause overflow when added.

MapFixed

The forbidden MAP_FIXED flag was specified.

MappingPastEof

A mapping with offset + length > EOF was attempted.

Mmap(Error)

The mmap call returned an error.

InvalidFileOffset

Invalid file offset.

MappedInAdvance

Memory mapped in advance.

MmapFlags(u32)

Invalid Xen mmap flags.

Fam(Error)

Fam error.

UnexpectedError

Unexpected error.

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

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

Returns 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>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl From<Error> for FromRangesError

fn from(source: MmapRegionError) -> Self

Converts to this type from the input type.
