Enum Error 

#[non_exhaustive]
pub enum Error {
    ParseError(String),
    UnknownNonTerminalError(String),
    InternalParserError(String),
    UnknownModifierError(String),
}

The tracery error type

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ParseError(String)

Error encountered while parsing a rule

UnknownNonTerminalError(String)

A referenced key does not exist

InternalParserError(String)

Internal parser error. This should only happen if the grammar and the parser are out of sync.

UnknownModifierError(String)

Unknown modifier.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
