Enum UpstreamClient 

pub enum UpstreamClient {
    Reqwest(Client),
}

Either the default reqwest client or a stealth (wreq) client, optionally wearing a different browser fingerprint per request via the UpstreamClient::StealthPool variant.

Variants

Reqwest(Client)

Default rustls-backed reqwest client. Carries SSRF resolver, redirect policy, proxy-pool, etc.

Implementations

impl UpstreamClient

pub fn from_reqwest(client: Client) -> Self

Build the default reqwest variant from a pre-configured client. All the SSRF/resolver/cookie wiring stays where it already is in main(); this is just the wrapping ctor.

pub fn stealth(_profile: ImpersonateProfile) -> Result<Self, UpstreamError>

Build a stealth variant wearing the given browser profile.

Errors

Returns UpstreamError::StealthFeatureDisabled if the binary was built without tls-impersonate.

pub fn stealth_pool( _profiles: &[ImpersonateProfile], ) -> Result<Self, UpstreamError>

Build a rotating pool of stealth clients (one per profile). send() advances a round-robin cursor so successive requests land on different fingerprints.

Errors

• UpstreamError::StealthFeatureDisabled if built without tls-impersonate.
• UpstreamError::Request if any client fails to build OR if _profiles is empty (a pool of zero is meaningless).

pub async fn send( &self, method: &str, url: &str, headers: &[(String, String)], body: Option<Vec<u8>>, max_body: usize, ) -> Result<UpstreamResponse, UpstreamError>

Send a request and read the response (with body bounded by max_body). Method/URL/headers/body shape mirrors what forward_wafrift_request already builds — the migration is just “stop calling client.request(method, url).send() directly, call this instead”.

Body bounding

Bodies are truncated at max_body bytes (no error, the truncated content is still useful for WAF-block detection — matches forward_wafrift_request’s existing semantics).

pub fn tls_stack_name(&self) -> &'static str

Returns the operator-visible name of the active TLS stack, for log lines / /_wafrift/status output.

Trait Implementations
