Errors produced by movie encode / decode / playback.

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.

HeaderTruncated

The blob is shorter than the fixed header.

Fields

expected: usize

Expected byte count.

got: usize

Actual byte count.

BadMagic

The magic prefix is wrong.

Fields

got: [u8; 8]

Bytes observed at the magic offset.

UnsupportedFormat

The container format version is outside the range we understand.

Fields

got: u16

Version we read.

max: u16

Highest version we accept.

UnsupportedFrameWidth

The header declared more bytes-per-frame than this build understands.

Fields

got: u8

Declared width.

max: u8

Width this build can parse.

BadRegion(u8)

The region byte is not a value this build understands.

Eof(usize)

The body (start point and/or input stream) ran past EOF.

BadSaveState(SnapshotError)

The embedded start-point save state failed to apply.

RomMismatch

The running ROM’s hash does not match the movie’s recorded hash.

Trait Implementations

impl Debug for MovieError

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

Formats the value using the given formatter.

impl Display for MovieError

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

Formats the value using the given formatter.

impl Error for MovieError

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<SnapshotError> for MovieError

fn from(source: SnapshotError) -> Self

Converts to this type from the input type.
