Error returned by save file decompression and parsing 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.

InvalidMagic

Block header magic mismatch.

Fields

offset: usize

found: u32

DecompressionFailed

LZ4 decompression failed for a block.

Fields

offset: usize

message: String

UnexpectedEof

File ended before the expected number of bytes could be read.

Fields

offset: usize

expected: usize

ChunkTooLarge

A block’s decompressed_size exceeds the maximum chunk size.

Fields

offset: usize

declared: u32

InvalidMetaLength

Metadata file has an invalid length (not one of the known sizes).

Fields

length: usize

MetaDecryptionFailed

Metadata decryption failed – magic sentinel not found after trying all slots.

UnsupportedMetaFormat

Metadata format version is unsupported (e.g., 2000/vanilla).

Fields

version: u32

Sha256Mismatch

SHA-256 verification failed.

Fields

expected: [u8; 32]

actual: [u8; 32]

MappingParseError

Failed to parse a mapping JSON file.

Fields

message: String

JsonParseError

Failed to parse save JSON.

Fields

message: String

Io(Error)

Wrapper for std::io::Error (file I/O).

Trait Implementations

impl Debug for SaveError

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

Formats the value using the given formatter.

impl Display for SaveError

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

Formats the value using the given formatter.

impl Error for SaveError

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 SaveError

fn from(source: Error) -> Self

Converts to this type from the input type.
