Enum StoreError

    WriterBusy {
        path: PathBuf,
    },
    EmptyExistingDocument {
        path: PathBuf,
    },
    SourceChanged {
        path: PathBuf,

Everything that can go wrong opening, reading or writing a store.

Variants

WriterBusy

Fields

path: PathBuf

EmptyExistingDocument

Fields

path: PathBuf

SourceChanged

Fields

path: PathBuf

InvalidSchema

Fields

path: PathBuf

reason: &'static str

PackageId(String, &'static str)

RecordKey(String, &'static str)

The record key could not be turned into a directory name (distinct from StoreError::PackageId so the message names which input was wrong).

Io

Fields

context: String

source: Error

Automerge

The stored bytes are not a loadable Automerge document. Boxed: unlike this crate’s other variants, AutomergeError alone is well over 100 bytes (nested enums carrying PatchAction, Strings, etc.), which would make every Result<_, StoreError> in this crate’s public API large regardless of which variant is actually returned.

Fields

path: PathBuf

source: Box<AutomergeError>

NewerSchema

The document was written by a newer build than this one. Kept separate from StoreError::Automerge because the data is intact and only this build is wrong for it — saying “unreadable” would lose that distinction.

Fields

path: PathBuf

found: u32

understood: u32

Migration

An app-owned migration declined an older, otherwise readable layout.

Fields

path: PathBuf

from: u32

to: u32

message: String

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<StoreError> for RecordOpenError

fn from(source: StoreError) -> RecordOpenError

Converts to this type from the input type.

impl From<StoreError> for StoreError

fn from(error: StoreError) -> StoreError

Converts to this type from the input type.

impl From<StoreError> for TransferError

fn from(source: StoreError) -> TransferError

Converts to this type from the input type.
