bool canPeek(size_t p);

void popFront();

void popFrontN(size_t n);

void incrementLine(size_t i);

Members

Functions

canPeek bool canPeek(size_t p)
empty bool empty(): Implements the range primitive empty.
front ubyte front(): Implements the range primitive front.
incrementLine void incrementLine(size_t i): Increments the range's line number and resets the column counter.
mark size_t mark()
peek const(ubyte)[] peek(size_t p)
peekAt ubyte peekAt(size_t offset)
popFront void popFront(): Implements the range primitive popFront.
popFrontN void popFrontN(size_t n): Implements the algorithm popFrontN more efficiently. This function does not detect or handle newlines.
seek void seek(size_t m): Sets the range to the given position.
slice const(ubyte)[] slice(size_t m): Returs a slice of the input byte array between the given mark and the current position. Params m = the beginning index of the slice to return
startsWith bool startsWith(const(ubyte[]) needle)

Variables

bytes const(ubyte)[] bytes;: The input bytes.
column size_t column;: The current column number.
index size_t index;: The range's current position.
line size_t line;: The current line number.
