The ability to dispatch fuchsia.net.dhcp.Server protocol requests and return a value.

Implementers of this trait can be used as the backing server-side logic of the fuchsia.net.dhcp.Server protocol. Implementers must maintain a store of DHCP Options, DHCP server parameters, and leases issued to clients, and support the trait methods to retrieve and modify these stores.

Required Methods

fn try_validate_parameters(&self) -> Result<&ServerParameters, Status>

Validates the current set of server parameters returning a reference to the parameters if the configuration is valid or an error otherwise.

fn dispatch_get_option(&self, code: OptionCode) -> Result<Option_, Status>

Retrieves the stored DHCP option value that corresponds to the OptionCode argument.

fn dispatch_get_parameter( &self, name: ParameterName, ) -> Result<Parameter, Status>

Retrieves the stored DHCP server parameter value that corresponds to the ParameterName argument.

fn dispatch_set_option(&mut self, value: Option_) -> Result<(), Status>

Updates the stored DHCP option value to the argument.

fn dispatch_set_parameter(&mut self, value: Parameter) -> Result<(), Status>

Updates the stored DHCP server parameter to the argument.

fn dispatch_list_options(&self) -> Result<Vec<Option_>, Status>

Retrieves all of the stored DHCP option values.

fn dispatch_list_parameters(&self) -> Result<Vec<Parameter>, Status>

Retrieves all of the stored DHCP parameter values.

fn dispatch_reset_options(&mut self) -> Result<(), Status>

Resets all DHCP options to have no value.

fn dispatch_reset_parameters( &mut self, defaults: &ServerParameters, ) -> Result<(), Status>

Resets all DHCP server parameters to their default values in defaults.

fn dispatch_clear_leases(&mut self) -> Result<(), Status>

Clears all leases from the store maintained by the ServerDispatcher.
