}

Errors returned by this transport.

Variants

Io(Error)

Filesystem/mapping I/O error.

IoAt

Filesystem/mapping I/O error with path context.

Fields

op: &'static str

Operation being performed.

path: PathBuf

Path involved in the IO.

source: Error

Underlying IO error.

Layout(Error)

Mapped bytes are not a compatible/initialized v1 layout.

RegionTooSmall

Backing file is smaller than the required bytes for the chosen layout/options.

Fields

needed: usize

Minimum required bytes.

found: usize

Mapped bytes found.

Misaligned

Mapping base address doesn’t meet the required layout alignment.

Fields

align: usize

Required alignment.

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.

impl From<Error> for Error

fn from(value: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(value: Error) -> Self

Converts to this type from the input type.
