frame_sequence_parser
A simple parser for frame sequences strings.
This will parse [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]
