This implements [`embedded-storage`](https://github.com/rust-embedded-community/embedded-storage) traits to access unencrypted ESP32 flash.

## Current support

ESP32, ESP32-C2, ESP32-C3, ESP32-C6, ESP32-H2, ESP32-S2 and ESP32-S3 are supported in `esp-storage`

## Important

For ESP32 it is necessary to build with [optimization level](https://doc.rust-lang.org/cargo/reference/profiles.html#opt-level) 2 or 3.

To make it work also for `debug` builds add this to your `Cargo.toml`

```toml
[profile.dev.package.esp-storage]
opt-level = 3
```

## Minimum Supported Rust Version (MSRV)
