Implementations

impl DeckSession

pub fn snapshot(&self) -> EditResult<DeckSnapshot>

pub fn insert_slide( &self, context: &EditCtx, index: u32, layout_part_path: Option<&str>, ) -> EditResult<SlideReceipt>

pub fn delete_slide( &self, context: &EditCtx, slide_id: &str, ) -> EditResult<SlideReceipt>

pub fn move_slide( &self, context: &EditCtx, slide_id: &str, to_index: u32, ) -> EditResult<SlideReceipt>

pub fn add_text_box( &self, context: &EditCtx, slide_id: &str, draft: &ShapeDraft, ) -> EditResult<ShapeReceipt>

pub fn add_shape( &self, context: &EditCtx, slide_id: &str, draft: &PresetShapeDraft, ) -> EditResult<ShapeReceipt>

pub fn set_shape_fill( &self, context: &EditCtx, slide_id: &str, shape_id: &str, color: Option<&str>, ) -> EditResult<ShapeFillReceipt>

pub fn set_shape_stroke( &self, context: &EditCtx, slide_id: &str, shape_id: &str, stroke: &ShapeStroke, ) -> EditResult<ShapeStrokeReceipt>

pub fn set_shape_adjust( &self, context: &EditCtx, slide_id: &str, shape_id: &str, adjustments: &BTreeMap<String, f64>, ) -> EditResult<ShapeAdjustReceipt>

pub fn remove_shape( &self, context: &EditCtx, slide_id: &str, shape_id: &str, ) -> EditResult<ShapeReceipt>

pub fn move_shape( &self, context: &EditCtx, slide_id: &str, shape_id: &str, x: i64, y: i64, ) -> EditResult<TransformReceipt>

pub fn resize_shape( &self, context: &EditCtx, slide_id: &str, shape_id: &str, width: i64, height: i64, ) -> EditResult<TransformReceipt>

impl DeckSession

pub fn save(&self) -> EditResult<Vec<u8>>

Serializes the deck with all edits applied. Untouched slides keep their exact source part bytes; edited slides are patched at the XML level.

impl DeckSession

pub fn story(&self, story_id: &str) -> EditResult<StorySnapshot>

pub fn insert_text( &self, context: &EditCtx, story_id: &str, index: u32, text: &str, style: &TextStyle, ) -> EditResult<TextReceipt>

pub fn delete_text( &self, context: &EditCtx, story_id: &str, start: u32, end: u32, ) -> EditResult<TextReceipt>

pub fn format_text( &self, context: &EditCtx, story_id: &str, start: u32, end: u32, patch: &TextStylePatch, ) -> EditResult<TextReceipt>

pub fn insert_paragraph_break( &self, context: &EditCtx, story_id: &str, index: u32, ) -> EditResult<TextReceipt>

impl DeckSession

pub fn open(bytes: &[u8], client_id: u64) -> EditResult<Self>

pub fn from_package(package: PptxPackage, client_id: u64) -> EditResult<Self>

Opens an edit session from an already parsed package. The fingerprint is taken from a re-zip of the package; prefer Self::from_package_with_source when the file bytes are at hand, so peers can match them against the update.

pub fn from_package_with_source( package: PptxPackage, source: &[u8], client_id: u64, ) -> EditResult<Self>

Opens an edit session from a parsed package, fingerprinting the file bytes it was parsed from.

pub fn open_from_update(update: &[u8], client_id: u64) -> EditResult<Self>

pub fn open_from_update_with_source( update: &[u8], source: &[u8], client_id: u64, ) -> EditResult<Self>

Like Self::open_from_update, but re-attaches the source file the update was seeded from, so the session can save. The bytes must hash to the fingerprint recorded in the update.

pub fn client_id(&self) -> u64

pub fn package(&self) -> &PptxPackage

pub fn yrs_doc(&self) -> &Doc

pub fn encode_state_vector_v1(&self) -> Vec<u8>

pub fn encode_state_as_update_v1(&self) -> Vec<u8>

pub fn encode_diff_v1(&self, remote_state_vector: &[u8]) -> EditResult<Vec<u8>>

pub fn apply_update_v1(&self, bytes: &[u8]) -> EditResult<DeckSnapshot>

pub fn observe_update_v1<F>(&self, callback: F) -> EditResult<Subscription>

where F: Fn(UpdateEvent) + 'static,

pub fn undo(&self) -> bool

pub fn redo(&self) -> bool

pub fn can_undo(&self) -> bool

pub fn can_redo(&self) -> bool

pub fn add_undo_barrier(&self)
