Struct FrameParams 

pub struct FrameParams {
    pub triggered: Option<i32>,
    pub current_image: Option<i32>,
    pub post_count: Option<i32>,
    pub actual_trigger_count: Option<i32>,
    pub soft_trigger: Option<i32>,
    pub control: Option<i32>,
    pub status: Option<&'static str>,
}

The parameter-library assignments C NDPluginCircularBuff::processCallbacks makes while handling one frame (NDPluginCircularBuff.cpp:120-203).

A field is Some exactly when C calls setIntegerParam/setStringParam for it on this frame, and None when C leaves the parameter untouched — which is how C freezes NDCircBuffCurrentImage at the pre-buffer size for the whole flush (it is assigned only on the pre-trigger branch, :151).

Later assignments in the same frame overwrite earlier ones, exactly as repeated setIntegerParam calls do before C’s single trailing callParamCallbacks(): on a frame that both flushes and completes, clients see only the final NDCircBuffPostCount = 0, never the intermediate count.

CircularBuffer::push — the state machine that decides the transitions — is the single owner of these values; the processor only maps them onto parameter indices. Reconstructing them from the post-push buffer state is what produced the divergences this type removes.

Fields

triggered: Option<i32>

NDCircBuffTriggered — C :127/:133 (every frame that evaluates the trigger) and :192/:194 (cleared when the sequence ends).

current_image: Option<i32>

NDCircBuffCurrentImage — C :151, the pre-buffer size, assigned ONLY on a pre-trigger frame.

post_count: Option<i32>

NDCircBuffPostCount — C :168-169 per forwarded post-trigger frame, and :193 (reset to 0) when the sequence re-arms.

actual_trigger_count: Option<i32>

NDCircBuffActualTriggerCount — C :179-180, incremented when the post-trigger count is reached, not when the trigger fires.

soft_trigger: Option<i32>

NDCircBuffSoftTrigger — C :191, the soft-trigger latch cleared on re-arm.

control: Option<i32>

NDCircBuffControl — C :190 (re-arm, still 1) and :197 (the preset trigger count was reached: C turns acquisition off).

status: Option<&'static str>

NDCircBuffStatus — C’s setStringParam calls (:152-153, :157, :194-195, :198).
