}

Errors that can occur when creating or accessing a MmapArray.

Variants

Io(Error)

An I/O error occurred (file open, read, write, flush, etc.).

InvalidMagic

The file does not start with the expected magic bytes b"MMAP".

VersionMismatch(u8)

The file header reports a format version other than 1.

DtypeMismatch

The dtype tag in the file does not match the requested element type.

Fields

expected: u8

actual: u8

ShapeMismatch

The stored shape does not match the shape provided by the caller.

Fields

expected: Vec<usize>

actual: Vec<usize>

NonContiguous

The source ndarray is not in contiguous C-order layout.

ReadOnly

The mapping is read-only and a mutable view was requested.

Trait Implementations

impl Debug for MmapError

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

Formats the value using the given formatter.

impl Display for MmapError

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

Formats the value using the given formatter.

impl Error for MmapError

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 MmapError

fn from(source: Error) -> Self

Converts to this type from the input type.
