Errors emitted by Store implementations.

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(Error)

Underlying I/O failure.

Deserialize(Error)

Malformed TOML or schema mismatch on read.

Serialize(Error)

Failed to serialize a Metadata to TOML.

LockTimeout

Could not acquire the advisory flock within the 5 s budget named in docs/STORE.md §4.

Fields

path: Utf8PathBuf

The lock-file path that was contended.

SchemaTooNew

The on-disk schema_version is a future major; per docs/STORE.md §3 the entry is read-only for this build.

Fields

theirs: String

Schema version observed on disk.

ours: String

Schema version this build supports.

MissingField

A reserved field that the spec marks as required is missing.

Fields

field: &'static str

The name of the missing reserved field.

PathTraversal

The supplied Safekey resolves to a path outside the store root. Defense-in-depth check; Safekey construction already enforces the [A-Za-z0-9._-]-only charset per docs/SAFEKEY.md.

Fields

path: Utf8PathBuf

The offending resolved path.

Trait Implementations

impl Debug for StoreError

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

Formats the value using the given formatter.

impl Display for StoreError

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

Formats the value using the given formatter.

impl Error for StoreError

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 StoreError

fn from(source: Error) -> Self

impl From<Error> for StoreError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for StoreError

fn from(source: Error) -> Self
