Expand description

WASM-facing portable viewer and bounded remote-range cache.

Implementations§

Source§

impl BrowserViewer

Source

pub fn new_default( width: u32, height: u32, range_budget_json: &str, ) -> Result<BrowserViewer, JsValue>

Creates a deterministic empty viewer for browser smoke tests and simple embeds.

Source

pub fn new( state_json: &str, range_budget_json: &str, ) -> Result<BrowserViewer, JsValue>

Creates a browser viewer from strict state and range-budget JSON.

Source

pub fn state_json(&self) -> Result<String, JsValue>

Returns strict portable viewer-state JSON.

Source

pub fn apply_input_json(&mut self, input_json: &str) -> Result<(), JsValue>

Applies one strict BrowserInput JSON object.

Source

pub fn plan_ranges_json( &mut self, ranges_json: &str, cancelled: bool, ) -> Result<String, JsValue>

Plans sorted/deduplicated bounded cache misses from a JSON range array.

Source

pub fn admit_range( &mut self, start: u64, end_exclusive: u64, bytes: &Uint8Array, ) -> Result<String, JsValue>

Explicitly copies a fetched JS byte array into the bounded WASM cache.

The returned JSON receipt reports the exact copied and evicted bytes.

Source

pub fn cached_range( &mut self, start: u64, end_exclusive: u64, ) -> Result<Option<Uint8Array>, JsValue>

Explicitly copies an exact cached range back into a JS byte array.
