Enum ProcessPredicate 

pub enum ProcessPredicate<'a> {
    Text(&'a FilterPattern),
    OwnedBy(u32),
    NotKernelThread,
    InSubtree(&'a [ProcessIdentity]),
}

One independently toggleable row test (§7.2).

Separating the three tests keeps them composable: the process screen ANDs whichever are active, the Time Lens contributor list reuses only the text one, and each can be unit-tested on its own.

Variants

Text(&'a FilterPattern)

The text query over name, command, PID, and user.

OwnedBy(u32)

The user-only toggle: keep rows owned by this uid.

NotKernelThread

The hide-kernel-threads toggle (Linux; §7.2).

InSubtree(&'a [ProcessIdentity])

Keep only the members of one followed subtree.

The membership is computed once per snapshot, by SubtreeUsage, and passed in as a sorted slice: descendancy is not a property of a single row, so unlike the other three predicates this one cannot be decided from the row alone.

It is a predicate rather than a step applied after filtering so that the existing machinery does the right thing for free — in tree mode ProcessTree::from_snapshot_filtered re-attaches a hidden process’s children to their nearest surviving ancestor, which for a subtree means the followed root becomes the root of what is drawn.
