Enum HostRequest 

#[non_exhaustive]
pub enum HostRequest<'a> {
    Init,
    SendCaPmt(&'a [u8]),
    MmiMenuAnswer(u8),
    MmiEnquiryAnswer(&'a [u8]),
    MmiCancel,

    DescramblePrograms(&'a [&'a [u8]]),
    AddProgram(&'a [u8]),

    Shutdown,
}

A request the host application makes of the stack.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Init

Bring the interface up: reset the slot and open the transport connection.

SendCaPmt(&'a [u8])

Send a serialized ca_pmt APDU body to the CAM’s conditional-access resource (descrambling request).

MmiMenuAnswer(u8)

Answer an MMI menu/list by 1-based choice_ref (0 = “back”/cancel), sent as menu_answ to the module.

MmiEnquiryAnswer(&'a [u8])

Answer an MMI enquiry with the user’s input text (EN 300 468 Annex A bytes), sent as answ (answ_id = answer).

MmiCancel

Abort the current MMI enquiry (answ with answ_id = cancel).

EnterMenu

Ask the module to open its MMI menu (enter_menu on the application_information session) — e.g. to read card / entitlement info.

Descramble(&'a [u8])

Descramble the services in a PMT section (raw dvb-si PMT bytes). The stack filters the PMT’s CA_descriptors to the CAM’s advertised CAIDs (from its ca_info) and sends a ca_pmt with list_management = only, cmd_id = ok_descrambling. The reply outcome surfaces as Notification::CaPmtReply.

DescramblePrograms(&'a [&'a [u8]])

Descramble a set of programmes in one CA-PMT list (first/more/ last, all ok_descrambling), replacing any prior set. Each element is a raw PMT section.

AddProgram(&'a [u8])

Add one programme to the descrambled set (list_management = add).

RemoveProgram(&'a [u8])

Remove one programme from the descrambled set (list_management = update, cmd_id = not_selected).

Shutdown

Tear the interface down (close sessions + transport connection).

Trait Implementations

impl<'a> Clone for HostRequest<'a>

fn clone(&self) -> HostRequest<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for HostRequest<'a>

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

Formats the value using the given formatter.

impl<'a> Eq for HostRequest<'a>

impl<'a> PartialEq for HostRequest<'a>

fn eq(&self, other: &HostRequest<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
