Enum HostControlEvent 

#[non_exhaustive]
pub enum HostControlEvent {
    Tune {
        network_id: u16,
        original_network_id: u16,
        transport_stream_id: u16,
        service_id: u16,
    },
    Replace {
        replacement_ref: u8,
        replaced_pid: u16,
        replacement_pid: u16,
    },
    ClearReplace {
        replacement_ref: u8,
    },
    AskRelease,
}

A host_control request the CAM makes of the host (ETSI EN 50221 §8.5.1, Tables 27-30). The runtime surfaces the decoded request; the host performs the retune / PID replacement itself (out of band) — there is no re-tune logic in 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.

Tune

tune() (Table 27): retune to the identified service.

Fields

network_id: u16

network_id.

original_network_id: u16

original_network_id.

transport_stream_id: u16

transport_stream_id.

service_id: u16

service_id.

Replace

replace() (Table 28): temporarily replace one component PID with another from the same multiplex.

Fields

replacement_ref: u8

replacement_ref — matched later by a Clear Replace.

replaced_pid: u16

13-bit replaced_PID.

replacement_pid: u16

13-bit replacement_PID.

ClearReplace

clear_replace() (Table 29): undo all Replace operations sharing this replacement_ref.

Fields

replacement_ref: u8

replacement_ref shared with one or more prior Replace requests.

AskRelease

ask_release() (Table 30): the CAM asks the host to release any replacements it holds (header-only request).

Trait Implementations

impl Clone for HostControlEvent

fn clone(&self) -> HostControlEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HostControlEvent

impl Debug for HostControlEvent

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

Formats the value using the given formatter.

impl Eq for HostControlEvent

impl PartialEq for HostControlEvent

fn eq(&self, other: &HostControlEvent) -> 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.
