Struct FetcherConfig

    pub headers: HashMap<String, String>,

Configuration for the HTTP fetcher.

This struct holds the default settings applied to every request made by a Fetcher or FetcherSession. Individual requests can override most of these via RequestConfig. Use FetcherConfigBuilder for a validated, fluent construction path.

Fields

impersonate: Impersonate

The browser impersonation profile to use. Controls which TLS and HTTP/2 fingerprint the client presents to the server. Defaults to Chrome.

stealthy_headers: bool

Whether to inject stealth headers (Referer, Sec-Ch-Ua, etc.) that make requests look like they come from a real browser. Enabled by default.

proxy: Option<Proxy>

An optional static proxy to route all requests through. If you need to rotate across multiple proxies, use a ProxyRotator instead.

timeout_secs: u64

Request timeout in seconds. Defaults to 30. Applies to the entire request lifecycle including DNS resolution, connection, and response body download.

headers: HashMap<String, String>

Default headers to include with every request. These are merged with per-request headers, with per-request values taking precedence on conflict.

retries: u32

Maximum number of retry attempts per request. Defaults to 3. Set to 1 to disable retries entirely.

retry_delay_secs: u64

Delay in seconds between retry attempts. Defaults to 1. This is a fixed delay, not exponential backoff.

follow_redirects: FollowRedirects

The redirect-following policy. Defaults to FollowRedirects::Safe.

max_redirects: usize

Maximum number of redirects to follow before giving up. Defaults to 30. Only applies when follow_redirects is not FollowRedirects::None.

verify: bool

Whether to verify TLS certificates. Defaults to true. Set to false only for testing against self-signed certificates – never in production.
