Enum TableType

pub enum TableType {
    LALR,
    LALR_PAGER,
    LALR_RN,
}

Specifies the type of the parsing table used during parsing to decide about shift/reduce/goto operations.

Variants

LALR

Lookahead LR tables. See http://publications.csail.mit.edu/lcs/pubs/pdf/MIT-LCS-TR-065.pdf

LALR_PAGER

A slight modification of LALR tables to prevent some reduce/reduce conflicts. Inspired by https://doi.org/10.1007/BF00290336

LALR_RN

LALR tables extended with right-nulled entries. Used for GLR parsing (RNGLR). See https://doi.org/10.1145/1146809.1146810

Trait Implementations

impl Clone for TableType

fn clone(&self) -> TableType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TableType

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

Formats the value using the given formatter.

impl Default for TableType

fn default() -> TableType

Returns the “default value” for a type.

impl PartialEq for TableType

fn eq(&self, other: &TableType) -> 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.

impl ValueEnum for TableType

fn value_variants<'a>() -> &'a [Self]

All possible argument values, in display order.

fn to_possible_value<'a>(&self) -> Option<PossibleValue<'a>>

The canonical argument value.

fn from_str(input: &str, ignore_case: bool) -> Result<Self, String>

Parse an argument into Self.

impl Eq for TableType
