Struct AtomicError 

pub struct AtomicError {
    pub step: AtomicStep,
    pub path: PathBuf,
    pub source: Option<Error>,
}

A failed atomic installation: which step, which path, and the OS error.

Fields

step: AtomicStep

The step that failed.

path: PathBuf

The path that step was about — the target, its temporary file, or the parent directory, depending on the step.

source: Option<Error>

The underlying OS error, absent only where the step had none.

Implementations

impl AtomicError

pub fn commit_uncertain(&self) -> bool

Whether the target may already carry the new bytes.

Only the final directory fsync can fail after the installation itself succeeded: the file is complete and in place, but its survival across a crash is unconfirmed. Every other step fails before the install and leaves the original untouched.

Trait Implementations

impl Debug for AtomicError

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

Formats the value using the given formatter.

impl Display for AtomicError

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

Formats the value using the given formatter.

impl Error for AtomicError

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.
