Float64Multiply returns a Lens that multiplies by x.

Float64ToInt returns a Lens that transforms a float64 value to the nearest int.

Float64ToString returns a Lens which transforms from float64 to string.

NewConst returns a Value of type t which always returns the value v, and gives an error when set.

NewLens creates a new Lens instance that transforms values from type T to type T1.

NewReflectiveLens creates a Lens from two dynamically typed functions.

NewValue creates a new Value with the given initial value and type.

Sender sends values from v down the channel c, which must be of type T where T is v.Type().

Transform returns a Value, v1, that mirrors an existing Value, v, by running m.Transform(x) on each value received from v.Iter(), and m.Reverse.Transform(x) on each value passed to v.Set().

UnitFloat64ToRangedFloat64 returns a Lens that peforms a linear transformation from a float64 value in [0, 1] to a float64 value in [lo, hi].

A Lens can transform from values of type T to values of type T1.

A Value represents a changing value of a given type.
