Crate rusty_esp_image 

rusty_esp_image — esp32-camera / esp_jpeg remade in Rust: sensor bring-up as data, DMA frame pools, pixel ops, JPEG/PNG via rusty_jpeg and rusty_png. Memory safe, no_std core.

This is the facade: it re-exports the no_std core and exposes the chip backends under esp. Depend on this crate; reach into the sub-crates only when you are building a backend.

Part of Janus (Remade With Rust). Plan: docs/plans/rusty_esp_image.md.

Modules

esp

Chip backends (esp-hal for Track B, esp-idf for Track A).

esp_core

rusty_esp_core — the shared vocabulary of the Janus ESP family.

jpeg

Reading a JPEG’s header without decoding it.

ops

Pixel operations — scalar, bounds-checked, and the oracle for every faster twin.

pool

A frame pool over one caller-owned buffer.

prelude

The names a sketch or firmware wants in scope.

sccb

SCCB — the camera control bus. It is I²C without a repeated start: a register read is a write transaction (the address) followed by a separate read transaction. Sensors use 8-bit (OV2640, OV7670) or 16-bit (OV5640, OV3660) register addresses.

sensor

Sensor identity and register tables — as data.

source

The capture seam.

Structs

FramePool

N equal slots carved from one buffer.

Mode

What a firmware asks a sensor for.

Register

One register write.

Sccb

A sensor’s control interface over an I²C bus.

SensorDesc

What a driver needs to find and address a sensor.

SlotId

Index of a slot in a FramePool.

TestPattern

A deterministic synthetic source: SMPTE-style colour bars with a moving marker, in Gray8, RGB565 or RGB888. It exists so a pipeline can be exercised on the host, and so a firmware can prove its wiring before a sensor is attached. Frame n is identical on every platform.

Enums

RegWidth

Register address width of a sensor.

SensorId

The sensors esp32-camera knows, with their product ids.

Constants

VERSION

Crate version, for capability manifests and logs.

Traits

ImageSource

Something that produces frames.
