Enum GreType 

#[repr(u8)]
pub enum GreType {
    End = 0,
    Alt = 1,
    RuleRef = 2,
    Char = 3,
    CharNot = 4,
    CharRngUpper = 5,
    CharAlt = 6,
    CharAny = 7,
    Token = 8,
    TokenNot = 9,
}

Element kinds, matching enum llama_gretype one for one.

The discriminants are llama.cpp’s, so a serialized grammar could be compared against upstream without a translation table.

Variants

End = 0

End of a rule definition.

Alt = 1

Start of an alternate definition for a rule.

RuleRef = 2

Non-terminal: a reference to another rule, by rule id.

Char = 3

Terminal: a single Unicode code point.

CharNot = 4

Inverted character set: [^a], [^a-b], [^abc].

CharRngUpper = 5

Modifies a preceding Char or CharAlt into an inclusive range ([a-z]).

CharAlt = 6

Modifies a preceding Char or CharRngUpper by adding another alternative to match ([ab], [a-zA]).

CharAny = 7

Any character (.).

Token = 8

Terminal: a token id (<[42]>).

TokenNot = 9

Inverted token (!<[42]>).

Implementations

impl GreType

pub fn is_char_element(self) -> bool

True for the element kinds that consume a character.

llama_grammar_is_char_element, used only by the printer and by rule validation.

pub fn is_stack_terminal(self) -> bool

True for the element kinds a parse stack may legally rest on.

llama_grammar_advance_stack aborts if a stack top is anything else; we return an error instead (see super::GrammarError).

Trait Implementations

impl Clone for GreType

fn clone(&self) -> GreType
