Struct acq_extra_t¶

Per-object extra header for an engine's cross-call state. More...

Detailed Description¶

The state blob is the only thing a fresh engine needs to continue a stream from (descriptor, state, input) — it makes the engine a pure transducer for the elastic fan-out (thread / process / pod). Standard bytes interface (see dp_state.h); layout, contiguous and flat:

[ dp_state_hdr_t ] [ acq_extra_t ] [ float complex unconsumed[n_unconsumed] ] (partial frame, < n samples) [ float nc_surface[n] ] (only when n_noncoh > 1)

Build the byte buffer with acq_state_bytes(); set_state validates the envelope (magic/version/size) plus n / n_noncoh below, rejecting a mismatch rather than reinterpreting it.

Public Attributes Documentation¶

variable _pad¶

uint16_t acq_extra_t::_pad;

variable has_nc¶

uint16_t acq_extra_t::has_nc;

1 if nc_surface[n] follows the samples.

variable n¶

uint64_t acq_extra_t::n;

Frame size; must equal engine's n.

variable n_noncoh¶

uint32_t acq_extra_t::n_noncoh;

Non-coherent looks (consistency).

variable n_unconsumed¶

uint32_t acq_extra_t::n_unconsumed;

Partial-frame samples that follow (< n).

variable nc_count¶

uint32_t acq_extra_t::nc_count;

Looks accumulated in the current dump.

variable samples_consumed¶

uint64_t acq_extra_t::samples_consumed;

Stream offset framed so far.
