Trait AsyncMediaSource 

pub trait AsyncMediaSource:
    Send
    + Sync
    + Debug {
    // Required methods
    fn source_id(&self) -> u64;
    fn produce(
        &self,
        buffer_id: u64,
        path: Option<PathBuf>,
        line_count: u32,
        text: String,
    ) -> MediaFuture<'_>;
}

An async, off-render-path producer of a buffer’s inline media blocks.

Required Methods

fn source_id(&self) -> u64

Stable id of the producing plugin — the teardown key. Two producers with the same id are the same plugin, so a reload replaces rather than duplicates.

fn produce( &self, buffer_id: u64, path: Option<PathBuf>, line_count: u32, text: String, ) -> MediaFuture<'_>

Produce this buffer’s media blocks off the render path. text is the buffer’s contents. Passed by value rather than through a document handle because a media scan reads EVERY line: a handle would cost one boundary crossing per line, where one copy costs one. The copy is affordable because this runs on open / edit, not per frame.

Dyn Compatibility

This trait is dyn compatible.

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