Enum HugeCommit 

pub enum HugeCommit {
    Nothing,
    Unchanged,
    Changed {
        cell: StateCellId,
        old: Bit4,
        new: Bit4,
        delta: Option<ChangeDelta>,
    },
    Full {
        cell: StateCellId,
        value: FourStateValue,
        revalidate: bool,
    },
}

What huge_commit decided; the caller (sched::kernel_adapter, which owns the scheduler hooks this crate layer cannot name) carries it out.

Variants

Nothing

Nothing was dirty.

Unchanged

The window’s words were stored and nothing changed.

Changed

The window’s words were stored and the value changed; old/new are bit 0 before and after (the only bit an edge event looks at).

Fields

cell: StateCellId

old: Bit4

new: Bit4

delta: Option<ChangeDelta>

The window’s old and new plane words, when wants_delta asked for them (a process waits on a select of this signal).

Full

The window could not be committed on its own (a forced cell or a change log): commit value (the whole signal) through SchedulerOps::commit_blocking_write, then call huge_commit_full_done.

Fields

cell: StateCellId

value: FourStateValue

revalidate: bool

Whether the mirror is still current once that write is done.
