Enum ConfigWriteError 

pub enum ConfigWriteError {
    Io {
        path: PathBuf,
        source: Error,
    },
    Invalid(String),
}

Failure modes of patch_key.

Variants

Io

Filesystem I/O failure during read, temp write, or atomic rename.

Fields

path: PathBuf

Path involved in the failed I/O operation (target or temp file).

source: Error

Underlying I/O error.

Invalid(String)

Validation rejected the request before any I/O. The string explains which constraint failed (e.g. “key must be non-empty”).

Trait Implementations

impl Debug for ConfigWriteError

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

Formats the value using the given formatter.

impl Display for ConfigWriteError

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

Formats the value using the given formatter.

impl Error for ConfigWriteError

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.
