verb / noun
abort
uh-BORT/əˈbɔːrt/
To bring a developing process to an end before completion.
The technician aborts the failed print before it is complete.

Etymology
On the OED's analysis, “amiss” and “be born” combine in a verb meaning “miscarry.” English extended this idea of interrupted development to deliberately ending a process or mission before completion.
In context
This is when the the user cancels the stream after they're done reading it. You get this cancel method. So I can use this to to abort the the interval.
