Struct NetworkPolicy 

pub struct NetworkPolicy {
    pub allow_hosts: Vec<String>,
    pub allow_request: Option<AllowCallback>,
    pub unrestricted: bool,
    pub resolver: Option<Resolver>,
    /* private fields */
}

Fields

allow_hosts: Vec<String>

Hosts (exact, case-insensitive) allowed even when their address class is blocked.

allow_request: Option<AllowCallback>

Called only for requests the defaults would block; true allows.

unrestricted: bool

Disable every check (trusted callers only).

resolver: Option<Resolver>

Replaces the system resolver (offline tests, pinned DNS, split-horizon setups).

Implementations

impl NetworkPolicy

pub fn unrestricted() -> Self

Policy with every check off.

pub fn allow_host(self, host: impl Into<String>) -> Self

pub fn with_resolver( self, f: impl Fn(&str) -> Vec<IpAddr> + Send + Sync + 'static, ) -> Self

pub fn allow_with( self, f: impl Fn(&NetworkRequest) -> bool + Send + Sync + 'static, ) -> Self

pub async fn check(&self, url: &str, resource_type: &str) -> Result<(), String>

Ok(()) when the request may proceed, otherwise the reason it is blocked.
