Locks are used to ensure that only a single thread can initialize the Lazy instance.

Initializer function can be called several times on concurrent access to uninitialized Lazy instance value, but only the first returned value will be used as the value of Lazy instance.

No locks are used to synchronize an access to the Lazy instance value; if the instance is accessed from multiple threads, its behavior is undefined.

Ensures that this value is not less than the specified minimumValue.

fun <T : Comparable<T>> T.coerceAtLeast(minimumValue: T): T

Ensures that this value is not greater than the specified maximumValue.

fun <T : Comparable<T>> T.coerceAtMost(maximumValue: T): T

Ensures that this value lies in the specified range minimumValue..maximumValue.

fun <T : Comparable<T>> T.coerceIn(
    minimumValue: T?, 
    maximumValue: T?
): T

Ensures that this value lies in the specified range.

fun <T : Comparable<T>> T.coerceIn(
    range: ClosedFloatingPointRange<T>
): T

fun <T : Comparable<T>> T.coerceIn(range: ClosedRange<T>): T

Creates a range from this Comparable value to the specified that value.

operator fun <T : Comparable<T>> T.rangeTo(
    that: T
): ClosedRange<T>
