Struct libwifi::frame::BlockAck

pub struct BlockAck {
    pub frame_control: FrameControl,
    pub duration: [u8; 2],
    pub source: MacAddress,
    pub destination: MacAddress,
    pub policy: bool,
    pub mode: BlockAckMode,
    pub acks: BlockAckInfo,
}

Used in a BlockAck session to request acknowledgment of sent packets.

Once the BlockAck session is established the AP and the requesting station can partake in a contention free burst within the scope of the session. After the frame burst is complete, the WLAN station will send a BlockAckRequest to the AP requesting the AP to acknowledge the frames the station just sent.

The AP will then respond with a BlockAck frame, acknowledging all received packets.

duration: [u8; 2]

source: MacAddress

destination: MacAddress

policy: bool

Trait Implementations

impl Addresses for BlockAck

fn src(&self) -> Option<&MacAddress>

Returns the sender of the Frame. This isn’t always send in every frame (e.g. CTS).

fn dest(&self) -> &MacAddress

Returns the destination of the Frame. This should always be present.

fn bssid(&self) -> Option<&MacAddress>

This isn’t always send in every frame (e.g. RTS).

impl Clone for BlockAck

fn clone(&self) -> BlockAck

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BlockAck

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

Formats the value using the given formatter.

impl From<BlockAck> for Frame

fn from(v: BlockAck) -> Frame

Converts to this type from the input type.

impl TryInto<BlockAck> for Frame

type Error = &'static str

The type returned in the event of a conversion error.

fn try_into(self) -> Result<BlockAck, <Self as TryInto<BlockAck>>::Error>

Performs the conversion.
