Struct BrowserAdapter 

pub struct BrowserAdapter { /* private fields */ }

Browser-based scraping adapter

Wraps stygian-browser’s BrowserPool to implement the ScrapingService port. Falls back to an error indicating unavailability when the browser pool cannot be used (headless Chrome not available, pool exhausted, etc.).

The adapter accepts per-request parameters via ServiceInput.params:

• wait_strategy: "dom_content_loaded" | "network_idle" | "selector:<css>" | "fixed_ms:<n>"
• stealth_level: "none" | "basic" | "advanced"
• timeout_ms: override default timeout in milliseconds
• wait_ms: milliseconds to wait when strategy is “fixed”

Implementations

impl BrowserAdapter

pub fn new() -> Self

Create a new BrowserAdapter with default configuration

Example

use stygian_graph::adapters::browser::BrowserAdapter;
use stygian_graph::ports::ScrapingService;

let adapter = BrowserAdapter::new();
assert_eq!(adapter.name(), "browser");

pub const fn with_config(config: BrowserAdapterConfig) -> Self

Create a new BrowserAdapter with custom configuration

Example

use stygian_graph::adapters::browser::{BrowserAdapter, BrowserAdapterConfig};
use std::time::Duration;

let config = BrowserAdapterConfig {
    timeout: Duration::from_secs(60),
    block_resources: false,
    ..BrowserAdapterConfig::default()
};
let adapter = BrowserAdapter::with_config(config);

Trait Implementations

impl Clone for BrowserAdapter

fn clone(&self) -> BrowserAdapter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for BrowserAdapter

fn default() -> Self

Returns the “default value” for a type.

impl ScrapingService for BrowserAdapter

fn execute<'life0, 'async_trait>( &'life0 self, input: ServiceInput, ) -> Pin<Box<dyn Future<Output = Result<ServiceOutput>> + Send + 'async_trait>>

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

Execute a JavaScript-rendered scrape

Accepts the following params keys:

• wait_strategy — how to determine page readiness
• stealth_level — anti-detection level
• timeout_ms — per-request timeout override

Example

use stygian_graph::adapters::browser::BrowserAdapter;
use stygian_graph::ports::{ScrapingService, ServiceInput};
use serde_json::json;

let adapter = BrowserAdapter::new();
let input = ServiceInput {
    url: "https://example.com".to_string(),
    params: json!({ "wait_strategy": "network_idle", "stealth_level": "advanced" }),
};
// let output = adapter.execute(input).await.unwrap();

fn name(&self) -> &'static str

Service name for identification in logs and metrics
