Type Alias: Predicate

Predicate = { all: true; } | { has: ColumnRef; } | { eq: readonly [ColumnRef, Scalar]; } | { in: readonly [ColumnRef, readonly Scalar[]]; } | { and: readonly Predicate[]; } | { or: readonly Predicate[]; } | { not: Predicate; }

Defined in: styles/types.ts:979

Which elements a rule applies to. Readers and the planner emit only all, has, not over has, eq and in (at most 8 values), with at most one and; a wider group is written onto the elements as a style column and selected with has. Open union.
