Types

type Modifier

type Modifier struct {
	Key modifier
	// Value will be type casted to one the expected types.
	// Modifier will panic if it doesn't match any of expected.
	Value any
}

type Op

type Op struct {
	// Prefix will be added before field name
	Prefix string
	Field  field
	Token  token
	// Value will be type casted to one the expected types.
	// Operation will panic if it doesn't match any of expected.
	Value any

	Group         []Op

	// CustomQuery is used to add custom query. If this is set, Field and Token will be ignored.
	// This is useful for complex queries that can't be expressed with Field and Token.
	// Value will be used for custom query if it's not nil.
	// Remember about setting correct bind index for Value.
