Errors that can occur when parsing a .puz file.

These represent critical issues that prevent successful parsing of the puzzle. Unlike PuzWarning, these errors cause parsing to fail completely.

Implementations

impl PuzError

pub fn with_position(self, position: u64) -> Self

Add position context to an existing error

pub fn with_context(self, context: &str) -> Self

Add context to an existing error

Trait Implementations

impl Clone for PuzError

fn clone(&self) -> PuzError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PuzError

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

Formats the value using the given formatter.

impl Display for PuzError

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

Formats the value using the given formatter.

impl Error for PuzError

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<Error> for PuzError

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<Utf8Error> for PuzError

fn from(error: Utf8Error) -> Self

Converts to this type from the input type.

impl PartialEq for PuzError

fn eq(&self, other: &PuzError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
