Error types that may occur when reading a CHD file or hunk.

This type tries to be ABI-compatible with libchdr, given sane defaults in the C compiler. See repr(C) in the Rustonomicon for more details.

Variants

None = 0

No error. This is only used by the C API bindings.

NoInterface = 1

No drive interface. This is only for C-compatibility purposes and is otherwise unused.

OutOfMemory = 2

Unable to allocate the required size of buffer.

InvalidFile = 3

The file is not a valid CHD file.

InvalidParameter = 4

An invalid parameter was provided.

InvalidData = 5

The data is invalid.

FileNotFound = 6

The file was not found.

RequiresParent = 7

This CHD requires a parent CHD that was not provided.

FileNotWriteable = 8

The provided file is not writable. Since chd-rs does not implement CHD creation, this is unused.

ReadError = 9

An error occurred when reading this CHD file.

WriteError = 10

An error occurred when writing this CHD file. Since chd-rs does not implement CHD creation, this is unused.

CodecError = 11

An error occurred when initializing a codec.

InvalidParent = 12

The provided parent CHD is invalid.

HunkOutOfRange = 13

The request hunk is out of range for this CHD file.

DecompressionError = 14

An error occurred when decompressing a hunk.

CompressionError = 15

An error occurred when compressing a hunk. Since chd-rs does not implement CHD creation, this is unused.

CantCreateFile = 16

Could not create the file. Since chd-rs does not implement CHD creation, this is unused.

CantVerify = 17

Could not verify the CHD. This is only for C-compatibility purposes and is otherwise unused.

NotSupported = 18

The requested operation is not supported. This is only for C-compatibility purposes and is otherwise unused.

MetadataNotFound = 19

The requested metadata was not found. This is only used by the C API bindings.

InvalidMetadataSize = 20

The metadata has an invalid size. This is only for C-compatibility purposes and is otherwise unused.

UnsupportedVersion = 21

The CHD version of the provided file is not supported by this library.

VerifyIncomplete = 22

Unable to verify the CHD completely. This is only for C-compatibility purposes and is otherwise unused.

InvalidMetadata = 23

The requested metadata is invalid.

InvalidState = 24

The internal state of the decoder/encoder is invalid. This is only for C-compatibility purposes and is otherwise unused.

OperationPending = 25

An operation is already pending. This is only for C-compatibility purposes and is otherwise unused.

NoAsyncOperation = 26

No async operations are allowed. This is only for C-compatibility purposes and is otherwise unused.

UnsupportedFormat = 27

Decompressing the CHD requires a codec that is not supported.

Unknown = 28

Unknown error.

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

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

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
