Variants

InvalidOffset

The offset is out of bounds or does not meet other restrictions.

BufferTooSmall

The provided buffer was too small to fit all the data it needs to fit.

PrematureEndOfInput

The input ended although it was expected to produce more data.

NoSuchBlock

The requested block is not present on the device.

NotImplemented

The requested function is not implemented for this I/O component.

NotFound

The requested entity is not present on the device or the registry does not hold an entry matching the criteria.

ExistsButShouldNot

An entry or entity was found, but there must not be one in order for the operation to continue or succeed.

BadAddress

The provided address is invalid.

DecodeError

An invalid value was encountered while decoding.

InvalidMagicNumber

The magic value in the data does not match the expected one.

IncoherentData

The data provided was not coherent or a checksum did not match the data.

InvalidArgument

The provided argument was invalid.

IsFile

The found entry is a file, but shouldn’t be.

IsDir

The found entry is a directory, but shouldn’t be.

IsSymLink

The found entry is a symbolic link, but shouldn’t be.

WriteError

An unexpected error occurred during the write, or the write couldn’t be completed.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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, _derive_more_display_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 PartialEq for Error

fn eq(&self, other: &Error) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
