Trait StaticSource 

pub trait StaticSource {
    // Required method
    async fn next(&mut self) -> Result<Option<Frame>, G2gError>;
}

A heap-free source: yields frames until the stream ends (Ok(None) at EOS).

The #[allow(async_fn_in_trait)] is intentional: this model targets a single executor (an Embassy task on an MCU, block_on on a host), so the auto-trait (Send) leakage the lint warns about is a non-issue, and avoiding it (a boxed or -> impl Future + Send return) would reintroduce the allocation this model exists to remove.

Required Methods

async fn next(&mut self) -> Result<Option<Frame>, G2gError>

Produce the next frame, or Ok(None) at end of stream.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
