Trait Implementations

impl Clone for ParserError

fn clone(&self) -> ParserError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParserError

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

Formats the value using the given formatter.

impl Display for ParserError

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

Formats the value using the given formatter.

impl Error for ParserError

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<Backtraced> for ParserError

fn from(source: Backtraced) -> Self

Converts to this type from the input type.

impl From<Formatted> for ParserError

fn from(source: Formatted) -> Self

Converts to this type from the input type.

impl From<ParserError> for LeoError

fn from(source: ParserError) -> Self

Converts to this type from the input type.

impl LeoMessageCode for ParserError

Implements the trait for LeoError Codes.

fn exit_code(&self) -> i32

Returns the error’s exit code for the program.

fn error_code(&self) -> String

Returns the prefixed error identifier.

fn warning_code(&self) -> String

Returns the prefixed warning identifier.

fn code_mask() -> i32

Returns the messages’s exit code mask, as to avoid conflicts.

fn message_type() -> String

Returns the message’s code type for the program.

fn is_error() -> bool

Returns if the message is an error or warning.

fn code_identifier() -> i8

The LeoErrorCode which has a default code identifier of 037 (Leo upsidedown and backwards). This is to make the exit codes unique to Leo itself.
