}

Per-request configuration overrides that take precedence over FetcherConfig defaults.

Every field is Option – when None, the corresponding value from the fetcher’s FetcherConfig is used instead. This lets you customize individual requests (e.g., use a different proxy or longer timeout) without affecting the global config.

Pass this to methods like Fetcher::get() and FetcherSession::post().

Fields

headers: Option<HashMap<String, String>>

Custom headers for this request. These are merged with the fetcher’s default headers, with per-request values taking precedence on name collisions.

cookies: Option<HashMap<String, String>>

Cookies to send with this request, serialized into a single Cookie header. In a FetcherSession, the session’s cookie jar is used in addition to these.

params: Option<HashMap<String, String>>

URL query parameters to append to the request URL.

timeout_secs: Option<u64>

Request timeout override in seconds. When set, this replaces the fetcher’s default timeout for this single request.

follow_redirects: Option<FollowRedirects>

Redirect policy override for this request.

max_redirects: Option<usize>

Maximum redirects override for this request.

retries: Option<u32>

Retry count override for this request. Set to Some(1) to disable retries.

retry_delay_secs: Option<u64>

Retry delay override in seconds for this request.

proxy: Option<Proxy>

Proxy override for this request. Overrides both the static proxy and the proxy rotator for this single request.

verify: Option<bool>

TLS verification override for this request.

impersonate: Option<Impersonate>

Browser impersonation override for this request.

stealthy_headers: Option<bool>

Stealth headers override for this request.

data: Option<Vec<u8>>

Raw request body bytes. Mutually exclusive with json – if both are set, json takes precedence.

json: Option<Value>

JSON request body. Automatically serialized and sent with a Content-Type: application/json header. Takes precedence over data.

auth: Option<(String, String)>

HTTP basic authentication credentials as (username, password).
