Struct IpGateConfig 

pub struct IpGateConfig { /* private fields */ }

The global IP gate: the parsed whitelist, blacklist, and exempt_ips lists.

Build it once at startup with IpGateConfig::new (which fails closed on an invalid entry) and evaluate request IPs with IpGateConfig::evaluate. The default value is three empty lists: the gate is inert, denying nobody and exempting nobody.

Implementations

impl IpGateConfig

pub fn new<W, B, E>( whitelist: W, blacklist: B, exempt_ips: E, ) -> Result<Self, IpGateError>

where W: IntoIterator, W::Item: AsRef<str>, B: IntoIterator, B::Item: AsRef<str>, E: IntoIterator, E::Item: AsRef<str>,

Parse and validate the three lists, failing closed on the first invalid entry.

Entry semantics match the reference whitelist matcher: a bare IP or a addr/prefix CIDR range, IPv4-mapped forms included, host bits cleared. The empty iterator is valid for any list.

Errors

Returns an IpGateError naming the list and the first entry that is neither a valid IP nor a valid CIDR range.

pub fn evaluate(&self, ip: IpAddr) -> IpGateVerdict

Evaluate a request IP against the gate.

The ordering is the reference contract’s: with a non-empty whitelist the whitelist gate decides (an unlisted, non-exempt IP is denied; an exempt IP does not pass the gate), otherwise the blacklist decides. The exemption flag is only set on an allowed verdict: it never adds a deny path and never removes one.
