len: u64

Requested length.

total: u64

Total size of the mapped file.

FlushFailed(String)

Error when a flush operation fails.

ResizeFailed(String)

Error when resizing is not allowed or fails.

AdviceFailed(String)

Error when memory advise fails.

LockFailed(String)

Error when lock operation fails.

UnlockFailed(String)

Error when unlock operation fails.

Trait Implementations

impl Debug for MmapIoError

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

Formats the value using the given formatter.

impl Display for MmapIoError

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

Formats the value using the given formatter.

impl Error for MmapIoError

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 MmapIoError

fn from(source: Error) -> Self

Converts to this type from the input type.
