ReversableRange

Range that allows to unify operations in forward and reverse directions without virtual function call overhead introduced by inputRangeObject.

reverseTransform is a function that will be applied to elements if range is iterated backwards.

struct ReversableRange (

alias reverseTransform = identity

R

) if (

isBidirectionalRange!R

) {

this(R range, bool reverse);

bool empty();

void popFront();

void popBack();

ReversableRange reverse();

static if(hasLength!R)

size_t length();

static if(isRandomAccessRange!R)

auto opIndex(size_t index);

static if(hasSlicing!R)

auto opSlice(size_t from, size_t to);

}

Constructors

this this(R range, bool reverse): Construct reversable range.

Functions

back auto back(): Bidirectional range primitives
empty bool empty()
front auto front(): Bidirectional range primitives
length size_t length(): If source range has length, the result also has length
opIndex auto opIndex(size_t index): If source range is a random access range, opIndex is defined
opSlice auto opSlice(size_t from, size_t to): Slicing is also propagated
popBack void popBack()
popFront void popFront(): Bidirectional range primitives
reverse ReversableRange reverse(): Reverse of this range
save auto save(): Bidirectional range primitives
