Struct StaticProxyProvider 

pub struct StaticProxyProvider { /* private fields */ }

Round-robin pool of statically-configured proxies. Baseline impl shipped with crawlberg.

Threadsafe; uses an AtomicUsize counter incremented per call. Empty pools always return None (direct connection).

Implementations

impl StaticProxyProvider

pub fn new(entries: Vec<ProxyConfig>) -> Self

Build a provider with the given pool. Order is preserved; rotation is round-robin starting from index 0.

pub fn empty() -> Self

Build an empty provider — always returns None. Useful as a default placeholder in substrate-only setups.

pub fn len(&self) -> usize

Number of proxies in the pool.

pub fn is_empty(&self) -> bool

true when no proxies are configured.

Trait Implementations

impl Debug for StaticProxyProvider

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

Formats the value using the given formatter.

impl ProxyProvider for StaticProxyProvider

fn next_proxy(&self, _host: &str) -> Option<ProxyConfig>

Pick a proxy for the given target host. host is the URL host string (no scheme, no port) — implementations may key on it for sticky per-host routing or ignore it for stateless rotation.
