Types

type Assigned

type Assigned struct {
	// contains filtered or unexported fields
}

Assigned associates a name with an expression.

func NewAssigned

func NewAssigned(name string, expr any) Assigned

NewAssigned creates a new named expression.

func (Assigned) Expression

func (n Assigned) Expression() any

Expr returns the expression.

func (Assigned) Name

func (n Assigned) Name() string

Name returns the name of the expression.

type Bound

type Bound[T any] struct {
	// contains filtered or unexported fields
}

Bound represents a bound. either exclusive or inclusive.

func NewBound

func NewBound[T any](value T, exclusive bool) *Bound[T]

NewBound creates a new bound.

func (*Bound[T]) Exclusive

func (b *Bound[T]) Exclusive() bool

Exclusive returns true if the bound is exclusive.

func (*Bound[T]) IsEmpty

func (b *Bound[T]) IsEmpty() bool

IsEmpty returns true if the bound is nil.

func (Bound[T]) Value

func (b Bound[T]) Value() T

Value returns the value of the bound.

type Exact

type Exact[T any] struct {
	// contains filtered or unexported fields
}

Exact represents an exact equality expression.

func NewExact

func NewExact[T any](value T) Exact[T]

NewExact creates a new equality expression.

	// contains filtered or unexported fields
}

Range represents a range of values of a sequential type.

func NewRange

func NewRange[T any](low, high *Bound[T]) Range[T]

NewRange creates a new range lookup expression.

func (Range[T]) High

func (r Range[T]) High() *Bound[T]

High returns the high bound of the range.

func (Range[T]) Low

func (r Range[T]) Low() *Bound[T]

Low returns the low bound of the range.

func (Range[T]) String

func (r Range[T]) String() string

String returns the string representation of the range.

type Set

type Set[T any] struct {
	// contains filtered or unexported fields
}
