This benchmark computes the sum of all rgb components in the image.
It measures the time and memory usage.
It does this using ImageBuffer, a streaming iterator optimized for RGB8 and
a streaming iterator with generic pixel type.
Run with:
> cargo run --release path/to/image.png
For this nasa image of 21600x10800 rgb pixels the results on my machine are:
Buffer:
pixel sum: [3341899515, 1612940354, 675870307]
time used: 7.231880666s, memory allocated (in kb): 683855
Incremental static:
pixel sum: [3341899515, 1612940354, 675870307]
time used: 8.606524099s, memory allocated (in kb): 490
Incremental dynamic:
pixel sum: [3341899515, 1612940354, 675870307]
time used: 9.765532836s, memory allocated (in kb): 490
Unsurprisingly the ImageBuffer version is slightly faster, but
uses a lot more memory, while the
