Enum StoreError 

#[non_exhaustive]
pub enum StoreError {
    IoError {
        operation: IoOperationKind,
        path: String,
        context: Option<String>,
        error: String,
    },
    HomeDirNotFound,
    FilenameEncoding {
        id: String,
        reason: String,
    },
    FormatConvert(FormatConvertError),
}

Error types for path and store 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.

IoError

File I/O error with detailed operation context.

Provides specific information about which I/O operation failed, along with optional context (e.g., “temporary file”, “after 3 retries”).

Fields

operation: IoOperationKind

The I/O operation that failed.

path: String

The file path where the error occurred.

context: Option<String>

Additional context (e.g., “temporary file”, “after 3 retries”).

error: String

The underlying I/O error message.

HomeDirNotFound

Failed to find home directory.

FilenameEncoding

Failed to encode or decode a filename for the given entity ID.

Raised when a filename encoding strategy (Direct/UrlEncode/Base64) cannot encode the ID on write, or cannot decode the stored filename on read.

Arguments

• id - The entity ID that could not be encoded/decoded.
• reason - A human-readable explanation of the failure.

Fields

id: String

The entity ID involved in the encoding failure.

reason: String

Human-readable reason for the failure.

FormatConvert(FormatConvertError)

Format conversion failed (e.g. JSON → TOML serialization error).

Wraps a FormatConvertError produced by local_store::format_convert.

Trait Implementations

impl Debug for StoreError

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

Formats the value using the given formatter.

impl Display for StoreError

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

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<FormatConvertError> for StoreError

fn from(source: FormatConvertError) -> StoreError

Converts to this type from the input type.

impl From<StoreError> for MigrationError

fn from(source: StoreError) -> Self

Converts to this type from the input type.
