Crate edgefirst_decoder_abi 

Layout-only C ABI contract for the EdgeFirst detection vocabulary.

Decoding model outputs into user-consumable structures — detection boxes, segmentation masks, tile placements — is what the decoder library is, so these types belong to it. They lived in edgefirst-tensor because of the r2 “plain-values-only boundary rule”, whose premise (sibling libraries never link each other) spec Revision 3 overturned. A plain value that crosses needs a shared DECLARATION, not a shared LINK.

Emitted into edgefirst/decoder.h by cbindgen’s [parse] include, exactly as edgefirst-tensor-abi’s types are emitted into tensor.h.

Structs

EfDetectBox

A detection: a normalized box, a score, and a label index.

EfMergeConfig

How overlapping detections from neighbouring tiles are merged.

EfSegmentation

One segmentation result, as plain values.

EfTilePlacement

C layout of ef_tile_placement in detect.h.

TilePlacement

One tile’s placement within a frame grid.
