Enum pest_debugger::DebuggerError

pub enum DebuggerError {
    Io(Error),
    MissingFilename,
    GrammarNotOpened,
    InputNotOpened,
    RunRuleFirst,
    EofReached,
    InvalidPosition(usize),
    IncorrectGrammar(String, Vec<Error<Rule>>),
    PreviousRunPanic(String),
}

Possible errors that can occur in the debugger context.

Variants

Io(Error)

Errors from opening files etc.

MissingFilename

When a filename can’t be extracted from a grammar path.

GrammarNotOpened

Running a debugger requires a grammar to be provided.

InputNotOpened

Running a debugger requires a parsing input to be provided.

RunRuleFirst

Continuing a debugger session requires starting a session by running a rule.

EofReached

Parsing finished (i.e. cannot continue the session).

InvalidPosition(usize)

Can’t create a Position in a given input.

IncorrectGrammar(String, Vec<Error<Rule>>)

The provided grammar is invalid. The first element contains a formatted error message. The second element (Vec) contains the errors.

PreviousRunPanic(String)

When restarting a session, the previous session seem to have panicked.

Trait Implementations

impl Debug for DebuggerError

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

Formats the value using the given formatter.

impl Display for DebuggerError

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

Formats the value using the given formatter.

impl Error for DebuggerError

fn source(&self) -> Option<&(dyn Error + 'static)>

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, demand: &mut Demand<'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 DebuggerError

fn from(source: Error) -> Self

Converts to this type from the input type.
