alloc_observe.Context

1/// A silent thread-bound nesting token that reserves an operation identifier2/// and participates in thread hierarchy tracking without publishing an event3/// upon completion. An active context updates the thread current operation ID,4/// links to the prior parent, and increments the shared active operation5/// counter. Callers must finish contexts in last-in, first-out order on the6/// originating thread, treating each token as having a single authoritative7/// owner. When observation is disabled, suppressed, or executed without an8/// installed sink, the returned context is inactive and reports an identifier9/// of zero.10pub const Context = if (enabled) EnabledContext else DisabledContext;
