Enum PartitionOfBoundsAst 

pub enum PartitionOfBoundsAst {
    Range {
        lower: Box<Expr>,
        upper: Box<Expr>,
    },
    List {
        values: Vec<Expr>,
    },
    Hash {
        modulus: u32,
        remainder: u32,
    },
    Default,
}

Variants

Range

FOR VALUES FROM (lower) TO (upper). Expr is ~144 bytes (lits include vector bodies), so we box both bounds to keep the variant size in line with Default for clippy and to minimise per-statement footprint when the partition shape isn’t in use.

Fields

lower: Box<Expr>

upper: Box<Expr>

List

v7.37.16 (16.1) — FOR VALUES IN (lit [, lit, …]). Each expr resolves to a typed literal at child-create time.

Fields

values: Vec<Expr>

Hash

v7.37.16 (16.2) — FOR VALUES WITH (MODULUS m, REMAINDER r). PG enforces 0 ≤ r < m; m must be positive.

Fields

modulus: u32

remainder: u32

Default
