Enum InvalidLayer

pub enum InvalidLayer {
    AttachFailed(Error),
    ReadCacheNotSupported,
    InvalidSectorSize(u32),
    MismatchedSectorSize {
        expected: u32,

}

An error returned when creating a DiskLayer.

Variants

AttachFailed(Error)

Failed to attach the layer

ReadCacheNotSupported

Read caching was requested but is not supported.

InvalidSectorSize(u32)

The sector size is invalid.

MismatchedSectorSize

The sector size of the layers do not match.

Fields

expected: u32

The expected sector size.

found: u32

The sector size found in the layer.

UselessWriteThrough

A write-through layer is preceeded by a layer that is not write-through, or the last layer is write-through.

ReadOnly

Writing to the layered disk would require this layer to be writable.

Trait Implementations

impl Debug for InvalidLayer

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

Formats the value using the given formatter.

impl Display for InvalidLayer

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

Formats the value using the given formatter.

impl Error for InvalidLayer

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
