Enum PartitionBound 

pub enum PartitionBound<X: Extension = NoExt> {
    List {
        values: ThinVec<Expr<X>>,
        meta: Meta,
    },
    Range {
        from: ThinVec<Expr<X>>,
        to: ThinVec<Expr<X>>,
        meta: Meta,
    },
    Hash {
        modulus: Literal,
        remainder: Literal,
        meta: Meta,
    },
    Default {
        meta: Meta,
    },
}

The partition-bound spec of a PartitionOf child (or an AttachPartition action): FOR VALUES {IN | FROM…TO | WITH} (…) or DEFAULT (PostgreSQL).

The bound datums are full a_exprs (PostgreSQL parses the minvalue/maxvalue range sentinels as ordinary column references at raw-parse time, so they need no dedicated node). The hash bound’s MODULUS m, REMAINDER r are unsigned integer literals validated in the grammar action — exactly one of each, either order — so they are modelled as a resolved pair rather than a raw option list (a missing/duplicate/non-integer value is a raw-parse error PostgreSQL raises, matched at the same layer).

Variants

List

FOR VALUES IN (<expr>, ...) — a list partition (≥ 1 value).

Fields

values: ThinVec<Expr<X>>

Values in source order.

meta: Meta

Source location and node identity.

Range

FOR VALUES FROM (<expr>, ...) TO (<expr>, ...) — a range partition (each side ≥ 1).

Fields

from: ThinVec<Expr<X>>

from in source order.

to: ThinVec<Expr<X>>

to in source order.

meta: Meta

Source location and node identity.

Hash

FOR VALUES WITH (MODULUS <n>, REMAINDER <n>) — a hash partition.

Fields

modulus: Literal

The MODULUS of a FOR VALUES WITH (MODULUS m, REMAINDER r) hash bound.

remainder: Literal

The REMAINDER of a hash partition bound.

meta: Meta

Source location and node identity.

Default

DEFAULT — the catch-all partition.

Fields

meta: Meta

Source location and node identity.

Trait Implementations
