Trait AsyncGutterDecorationSource 

pub trait AsyncGutterDecorationSource:

    + Debug {
    // Required methods
    fn source_id(&self) -> u64;
    fn produce(
        &self,
        buffer_id: u64,
        path: Option<PathBuf>,
        line_count: u32,
    ) -> DecorationFuture<'_>;
}

An async, off-render-path producer of a buffer’s gutter decorations.

The renderer NEVER calls this. The host’s per-tick decoration pump drives it on a trigger, writes the result into the per-buffer cache, and the renderer merges the cached marks into the same gutter partition it walks for Mode::gutter_decorations.

Required Methods

fn source_id(&self) -> u64

Stable id of the producing plugin — the teardown key (GutterDecorationSourceRegistry::unregister). Two producers with the same id are the same plugin (reload replaces rather than duplicates).

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

Produce this buffer’s gutter decorations off the render path. path is the buffer’s on-disk path when it has one (a provider may key marks off it); line_count bounds the addressable lines. See DecorationFuture for the Ok/Err contract.

Dyn Compatibility

This trait is dyn compatible.

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