Struct FetchParams 

pub struct FetchParams {
    pub google_search: Option<bool>,
    pub timeout_ms: Option<f64>,
    pub wait_ms: Option<u64>,
    pub extra_headers: Option<HashMap<String, String>>,
    pub disable_resources: Option<bool>,
    pub network_idle: Option<bool>,
    pub load_dom: Option<bool>,
    pub wait_selector: Option<String>,
    pub wait_selector_state: Option<WaitState>,
    pub blocked_domains: Option<HashSet<String>>,
    pub solve_cloudflare: Option<bool>,
    pub selector_config: Option<HashMap<String, Value>>,
}

Per-fetch parameter overrides – a subset of BrowserConfig that can be changed on a per-request basis.

Every field is Option – when None, the value falls back to the session’s BrowserConfig. Pass a FetchParams to [DynamicSession::fetch] or [StealthySession::fetch] to override specific settings for a single navigation without modifying the session-wide configuration.

Fields

google_search: Option<bool>

Override the Google-search warm-up flag for this request.

timeout_ms: Option<f64>

Override the navigation timeout in milliseconds.

wait_ms: Option<u64>

Override the post-load sleep delay in milliseconds.

extra_headers: Option<HashMap<String, String>>

Override the extra HTTP headers for this request.

disable_resources: Option<bool>

Override the resource-blocking flag for this request.

network_idle: Option<bool>

Override the network-idle wait flag for this request.

load_dom: Option<bool>

Override the DOM-content-loaded wait flag for this request.

wait_selector: Option<String>

CSS selector to wait for before returning, overriding the config default.

wait_selector_state: Option<WaitState>

Required state of the wait selector, overriding the config default.

blocked_domains: Option<HashSet<String>>

Override the set of blocked domains for this request.

solve_cloudflare: Option<bool>

Enable Cloudflare challenge solving for this request.

selector_config: Option<HashMap<String, Value>>

Override selector-engine configuration for this request.

Implementations

impl FetchParams

pub fn merge_with_config(&self, config: &BrowserConfig) -> ResolvedFetchParams

Merge these optional overrides with the base BrowserConfig to produce resolved values.

For each field, if the FetchParams value is Some, it wins; otherwise the corresponding BrowserConfig value is used. The result is a ResolvedFetchParams with no Option fields, ready for immediate use during navigation.

Trait Implementations

impl Clone for FetchParams

fn clone(&self) -> FetchParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FetchParams

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

Formats the value using the given formatter.

impl Default for FetchParams

fn default() -> FetchParams

Returns the “default value” for a type.
