frame-sequence

A simple parser for frame sequences strings.

This will parse a str describing a sequence of frames into a Vec<isize> containing individual frame numbers.

Mainly intended/useful for rendering/animation applications.

Example Frame Sequence Strings

Individual frames:

1,2,3,5,8,13[1, 2, 3, 5, 8, 13]

A sequence:

10-15[10, 11, 12, 13, 14, 15]

With step size:

10-20@2[10, 12, 14, 16, 18, 20]

Step size must be always positive.

To get a sequence backwards specify the range in reverse:

42-33@3[42, 39, 36, 33]

With binary splitting:

10-20@b[10, 20, 15, 12, 17, 11, 13, 16, 18, 14, 19]

The last frame of a sequence will be omitted if the specified step size does not touch it:

80-70@4[80, 76, 72]
