Expand description
A vector of progress updates in logs
This exists to support upcasting of the concrecte progress update vectors to
dyn ProgressEventTimestamp
. Doing so at the vector granularity allows us to
use a single allocation for the entire vector (as opposed to a Box
allocation
for each dynamically typed element).
