Struct ImageFileMediaSource 

pub struct ImageFileMediaSource;

The media producer that draws an image-mode buffer’s own file.

The mode owns its picture the way org owns its inline ones: through the media-source registry, off the render path, sized and decoded by the host. There is no image-specific code in the renderer or the host because of it — an image-mode buffer is one block anchored at line 0, which is the same thing an org buffer produces several of.

Trait Implementations

impl AsyncMediaSource for ImageFileMediaSource

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.

impl Debug for ImageFileMediaSource

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
