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

An I/O operation failed against a known path.

Fields

path: PathBuf

Path involved in the failed operation.

source: Error

The underlying OS error.

BareIo(Error)

An I/O operation failed without an associated path.

BadMagic

A page or file carried the wrong magic number — a different file kind, or not a Quiver file at all.

Fields

expected: u32

The magic the reader expected.

found: u32

The magic actually found on disk.

UnsupportedVersion

The on-disk format version is not understood by this build.

Fields

found: u16

Version read from disk.

supported: u16

Highest version this build can read.

PageCorrupt

A page failed its CRC32C check — corruption or tampering was detected.

Fields

page_id: u64

Page id from the (possibly damaged) header.

expected: u32

CRC stored in the page header.

computed: u32

CRC recomputed over the page contents.

MalformedPage(String)

A page or file header was structurally invalid (impossible length, unknown page type, out-of-order page id, …).

Serialization(Error)

Serialization or deserialization of a metadata structure failed.

TooLarge(String)

A value exceeded a hard structural limit (e.g. a payload larger than a page body, or a WAL record over the size cap).

NotFound(String)

A referenced collection or record does not exist.

AlreadyExists(String)

A resource that must be unique already exists (e.g. a collection name).

InvalidArgument(String)

A caller supplied an invalid argument (e.g. a vector of the wrong dim).

Implementations

impl CoreError

pub fn io(path: impl AsRef<Path>, source: Error) -> Self

Build an CoreError::Io tagged with the path it occurred on.

Trait Implementations

impl Debug for CoreError

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

Formats the value using the given formatter.

impl Display for CoreError

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

Formats the value using the given formatter.

impl Error for CoreError

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 CoreError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for CoreError

fn from(source: Error) -> Self

Converts to this type from the input type.
