Struct PersistAtomicError 

pub struct PersistAtomicError {
    pub error: Error,
    pub file: NamedTempFile,
}

Error returned by NamedTempFile::persist_atomic when the atomic-persist sequence fails partway through.

The underlying io::Error is in PersistAtomicError::error and the original NamedTempFile is in PersistAtomicError::file, preserved so the caller can retry or fall back to other cleanup logic without losing the source.

Example

use mod_tempdir::{NamedTempFile, PersistAtomicError};

fn persist_or_log(f: NamedTempFile, target: &str) {
    match f.persist_atomic(target) {
        Ok(landed) => println!("persisted to {}", landed.display()),
        Err(PersistAtomicError { error, file }) => {
            eprintln!("persist failed: {error}");
            // `file` is the original NamedTempFile, intact.
            // It will be cleaned up on Drop, or you can retry.
            drop(file);
        }
    }
}

Fields

error: Error

The underlying I/O error that aborted the atomic persist.

file: NamedTempFile

The NamedTempFile that would have been moved, returned intact so the caller can retry or drop it.

Trait Implementations

impl Debug for PersistAtomicError

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

Formats the value using the given formatter.

impl Display for PersistAtomicError

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

impl Error for PersistAtomicError

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<PersistAtomicError> for Error

fn from(e: PersistAtomicError) -> Self

Converts to this type from the input type.
