Enum TableError 

pub enum TableError {
    EofIsError,
    EofNotSentinel {
        eof: u16,
        token_count: u32,
        external_count: u32,

Errors related to parse table validation

Variants

EofIsError

The EOF symbol ID collides with the built-in ERROR symbol.

EofNotSentinel

EOF symbol ID is too low; it must be a sentinel beyond all tokens.

Fields

eof: u16

token_count: u32

external_count: u32

EofMissingFromIndex

The EOF symbol is not registered in the symbol-to-index mapping.

EofParityMismatch(u16)

ACTION table EOF column has mismatched accept/reduce entries.

Trait Implementations

impl Debug for TableError

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

Formats the value using the given formatter.

impl Display for TableError

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

Formats the value using the given formatter.

impl Error for TableError

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.
