Enum Error 

#[non_exhaustive]
pub enum Error {
    Io(Error),
    UnknownFormat,
    PartitionedDisk(PartitionTableKind),
    UnsupportedFormat(BlockFormat),
    DetectedFormatMismatch {
        detected: FatVariant,
        opened: FatVariant,
    },
    Fat(Error),
}

Error returned by category-level block operations.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Io(Error)

The source could not be read or repositioned.

UnknownFormat

No supported format was recognized.

PartitionedDisk(PartitionTableKind)

The source is a partitioned disk rather than a directly openable volume.

UnsupportedFormat(BlockFormat)

The detected format has no category-level opener enabled.

DetectedFormatMismatch

Cheap detection and full filesystem validation disagreed.

Fields

detected: FatVariant

Format reported by lightweight detection.

opened: FatVariant

Format reported after the filesystem was fully opened.

Fat(Error)

FAT validation failed.

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, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

Available on crate feature std only.

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(error: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error
