Snapshot

Wrapper for a snapshot type, which is a type that keeps track of a type's value history.

final

class Snapshot (

T

) if (

is(T == struct) ||

isScalarType!T

) {

this(T initValue);

T value [@property setter];

T value [@property getter];

void prev(size_t states);

void reset();

T opIndex(size_t index);

static if(isScalarType!T)

int opCmp(T comparison);

static if(isScalarType!T)

bool opEquals(T comparison);

}

Constructors

this this(): Creates a new snapshot of a type.
this this(T initValue): Creates a new snapshot of a type.

Alias This

Alias this to set the value directly for the snapshot.

Members

Functions

opCmp int opCmp(T comparison): Operator overload for comparing scalar types.
opEquals bool opEquals(T comparison): Operator overload for equality comparison between scalar types.
opIndex T opIndex(size_t index): Operator overload for indexing to retrieve a specific historical snapshot of the type.
prev void prev(): Rolls back to the previous value.
prev void prev(size_t states): Rolls back a specific amount of states.
reset void reset(): Resets the value to its first known value.

Properties
