Enum StateError 

pub enum StateError {
    Load {
        file: PathBuf,
        detail: String,
    },
    Save {
        file: PathBuf,
        detail: String,
    },
    Remove {
        file: PathBuf,
        detail: String,
    },
}

A failure to read, write or remove the state file.

The messages are the Czech ones the Python version prints, followed by a detail that says what went wrong.

Implementations

impl StateError

pub fn file(&self) -> &Path

The state file the error is about.

pub fn detail(&self) -> &str

What went wrong, without the leading sentence.

Trait Implementations

impl Debug for StateError

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

Formats the value using the given formatter.

impl Display for StateError

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

Formats the value using the given formatter.

impl Error for StateError

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<StateError> for Failure

fn from(error: StateError) -> Self

Converts to this type from the input type.
