pub struct AdapterTracePage { /* private fields */ }

A TracePage over any EngineAdapter.

Implementations

impl AdapterTracePage

pub fn new(adapter: Arc<dyn EngineAdapter>) -> Self

Trace the page behind adapter.

Trait Implementations

impl Clone for AdapterTracePage

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl TracePage for AdapterTracePage

fn context_key(&self) -> Option<usize>

An adapter drives one page in its own context, so they share a key.

fn require_feature(&self, feature: &str) -> Result<(), EngineError>

fn engine(&self) -> Option<String>

The engine’s name, written to the manifest unless the options name one.

fn page_key(&self) -> Option<usize>

A value that is the same every time this page is traced.

fn has_context(&self) -> bool

Whether the page belongs to a browser context a record can name.

fn evaluate_function<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, source: &'life1 str, argument: &'life2 Json, ) -> Pin<Box<dyn Future<Output = Result<Json, String>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Call the JavaScript function source with argument in the page and return what it resolved to, with object keys in the page’s order.

fn screenshot<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Option<Vec<u8>>, String>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

A PNG of the page, or None when the engine cannot take one.

fn add_init_script<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, source: &'life1 str, argument: &'life2 Json, ) -> Pin<Box<dyn Future<Output = Result<Option<String>, String>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Run source with argument before the code of every future document.

fn remove_init_script<'life0, 'life1, 'async_trait>( &'life0 self, identifier: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<(), String>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Undo TracePage::add_init_script.

fn events<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Option<BoxStream<'static, TraceEngineEvent>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Page activity the trace records as it happens, when the engine reports any.
