Expand description

The filtering API.

Implementations§

Source§

impl<C> FilterApi<C>

Source

pub fn new(ctx: C) -> Self

Creates a new FilterApi from a context pair.

Source§

impl<C> FilterApi<C>
where C: ContextPair, C::CoreContext: FilterContext<C::BindingsContext> + FilterIpContext<Ipv4, C::BindingsContext> + FilterIpContext<Ipv6, C::BindingsContext>, C::BindingsContext: FilterBindingsTypes,

Source

pub fn set_filter_state<RuleInfo: Clone>( &mut self, v4: Routines<Ipv4, <C::BindingsContext as FilterBindingsTypes>::DeviceClass, RuleInfo>, v6: Routines<Ipv6, <C::BindingsContext as FilterBindingsTypes>::DeviceClass, RuleInfo>, ) -> Result<(), ValidationError<RuleInfo>>

Sets the filtering state for the provided IP version.

The provided state must not contain any cyclical routine graphs (formed by rules with jump actions). The behavior in this case is unspecified but could be a deadlock or a panic, for example.

§Panics

Panics if the provided state includes cyclic routine graphs.

Source

pub fn inspect_state<N: Inspector>(&mut self, inspector: &mut N)

Exports filtering state into inspector.
