Enum vm_memory::mmap::MmapRegionError

pub enum MmapRegionError {
    InvalidOffsetLength,
    InvalidPointer,
    MapFixed,
    MappingOverlap,
    MappingPastEof,
    Mmap(Error),
    SeekEnd(Error),
    SeekStart(Error),
}

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

Variants

InvalidOffsetLength

The specified file offset and length cause overflow when added.

InvalidPointer

The specified pointer to the mapping is not page-aligned.

MapFixed

The forbidden MAP_FIXED flag was specified.

MappingOverlap

Mappings using the same fd overlap in terms of file offset and length.

MappingPastEof

A mapping with offset + length > EOF was attempted.

Mmap(Error)

The mmap call returned an error.

SeekEnd(Error)

Seeking the end of the file returned an error.

SeekStart(Error)

Seeking the start of the file returned an 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, f: &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.
