Struct AsyncWriteAllOperationFailure 

pub struct AsyncWriteAllOperationFailure { /* private fields */ }

Error returned by an owning asynchronous whole-file write.

Recovery ownership remains in the operation even when this error is consumed.

Examples

use qubit_fs::Path;
use qubit_fs::write::WriteOptions;
use qubit_fs::write::AsyncWriterRecovery;
use qubit_fs::write::WriteFailureState;
let mut operation = filesystem.begin_write_all(
    Path::parse("/report")?, b"bytes".to_vec(), WriteOptions::default(),
)?;
let failure = operation.execute().await.expect_err("fixture commit failure");
assert_eq!(WriteFailureState::NotPublished, failure.state());
assert_eq!(5, failure.written_bytes());
assert!(operation.has_recovery());
let cleanup = match operation.recovery().expect("retained session") {
    AsyncWriterRecovery::Opened(writer) => writer.abort_async().await,
    AsyncWriterRecovery::Rejected(writer) => writer.abort_async().await,
};
assert!(cleanup.is_ok());
// Application error handling can retain `failure`, `cleanup`, and `operation`.

Implementations

impl AsyncWriteAllOperationFailure

pub const fn error(&self) -> &FsError

Returns the contextual filesystem error.

pub const fn state(&self) -> WriteFailureState

Returns the publication facts recorded when execution stopped.

pub const fn written_bytes(&self) -> u64

Returns bytes acknowledged by completed writes before execution stopped.

pub fn into_error(self) -> FsError

Consumes the failure and returns its filesystem error.

This discards publication state and confirmed byte count. The operation still owns any recovery writer; prefer into_parts when recovering.

pub fn into_parts(self) -> (FsError, WriteFailureState, u64)

Consumes the failure and returns all recovery facts.

Trait Implementations

impl Debug for AsyncWriteAllOperationFailure

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

Formats the value using the given formatter.

impl Display for AsyncWriteAllOperationFailure

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

Formats the value using the given formatter.

impl Error for AsyncWriteAllOperationFailure

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.
