Struct Failure 

#[non_exhaustive]
pub struct Failure {
    pub stage: Stage,
    pub emitted: u64,
    pub cause: Box<dyn Error + Send + Sync>,
}

Terminal failure with original cause and confirmed append progress. emitted excludes overwrites; a failed patch may have partial effects.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

stage: Stage

Stage of the failure.

emitted: u64

Confirmed appended bytes, including any partial failed write.

cause: Box<dyn Error + Send + Sync>

Original I/O, native codec, cancellation or protocol error.

Trait Implementations

impl Debug for Failure

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

Formats the value using the given formatter.

impl Display for Failure

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

Formats the value using the given formatter.

impl Error for Failure

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.
