Struct PersistError 

pub struct PersistError {
    pub error: Error,
    pub path: PathBuf,
}

The error returned by crate::TempFile::persist and crate::TempDir::persist when the move to the target path fails.

On failure the temporary file or directory is not deleted: it is left in place at PersistError::path so the caller can recover the data instead of losing it. To restore automatic cleanup, re-wrap that path with from_existing(path, Ownership::Owned).

There is intentionally no From<PersistError> for Error conversion: a blanket ? would silently drop PersistError::path, the one piece of information that makes recovery possible. Handle the two fields explicitly, or use map_err(|e| e.error) if you only care about the underlying error.

Fields

error: Error

The underlying error that prevented the move (for example a cross-device rename, a permission error, or a missing target directory).

path: PathBuf

The path at which the temporary file or directory still resides.

Trait Implementations

impl Debug for PersistError

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

Formats the value using the given formatter.

impl Display for PersistError

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

Formats the value using the given formatter.

impl Error for PersistError

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>)
