Errors for manifest file.

Variants

BadMagicText

Manifest has bad magic.

BadExternalMagic

Cannot open manifest because the external magic doesn’t match.

Fields

expected: u16

Expected external magic.

found: u16

Found external magic.

BadMagic

Cannot open manifest because the magic doesn’t match.

Fields

expected: u16

Expected magic.

found: u16

Found magic.

ChecksumMismatch

Corrupted manifest file: entry checksum mismatch.

EntryTooLarge

Corrupted manifest file: not enough bytes to decode manifest entry.

Fields

len: u32

Entry data len.

remaining: u32

Remaining file size.

Data(<M::Data as Data>::Error)

Encode/decode data error.

Manifest(M::Error)

Manifest error.

IO(F::Error)

I/O error.

Implementations

impl<F: BackedFile, M: BackedManifest> Error<F, M>

pub const fn io(err: F::Error) -> Self

Create a new Error from an I/O error.

pub const fn data(err: <M::Data as Data>::Error) -> Self

Create a new Error from a data error.

pub const fn manifest(err: M::Error) -> Self

Create a new Error from an unknown manifest event.

Trait Implementations

impl<F: Debug + BackedFile, M: Debug + BackedManifest> Debug for Error<F, M>

where M::Data: Debug, M::Error: Debug, F::Error: Debug,

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

Formats the value using the given formatter.

impl<F: BackedFile, M: BackedManifest> Display for Error<F, M>

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

Formats the value using the given formatter.

impl<F: BackedFile, M: BackedManifest> Error for Error<F, M>

where Self: Debug + Display,

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>)
