Enum RepetitionQuantifier 

pub enum RepetitionQuantifier {
    ZeroOrMore,
    OneOrMore,
    AtMostOne,
    Exactly(u32),
    AtLeast(u32),
    AtMost(u32),
    Range(u32, u32),
}

A row-pattern quantifier — the repetition count applied to a pattern factor.

A tag enum (its bounds are plain u32s, no spanned children). Mirrors sqlparser-rs verbatim. The AtMostOne (?) form has no lexer-reachable parser path — see the module docs — but is retained for parity and lossless rendering.

Variants

ZeroOrMore

* — zero or more.

OneOrMore

+ — one or more.

AtMostOne

? — zero or one.

Exactly(u32)

{n} — exactly n.

AtLeast(u32)

{n,} — at least n.

AtMost(u32)

{,m} — at most m.

Range(u32, u32)

{n,m} — between n and m (inclusive).

Trait Implementations
