Struct Downlink 

pub struct Downlink<'a> { /* private fields */ }

A downlink data frame to encode, built up from the fields a sender sets.

Construct one with new and turn on whatever applies; the rest default off.

Implementations

impl<'a> Downlink<'a>

pub fn new(fcnt: u32, fport: u8, payload: &'a [u8]) -> Self

Creates an unconfirmed downlink with no options set.

Arguments

• fcnt - the frame counter for this downlink.
• fport - the port; 0 for MAC commands, otherwise an application port.
• payload - the application payload to carry.

Returns

The downlink.

pub fn confirmed(self) -> Self

Marks the downlink as confirmed, asking the device to acknowledge it.

Returns

The downlink, for chaining.

pub fn with_adr(self) -> Self

Sets the adaptive-data-rate bit.

Returns

The downlink, for chaining.

pub fn with_ack(self) -> Self

Sets the acknowledgement bit, confirming a previously received uplink.

Returns

The downlink, for chaining.

pub fn with_fpending(self) -> Self

Sets the frame-pending bit, signalling more downlinks are waiting.

Returns

The downlink, for chaining.

pub fn with_fopts(self, fopts: &'a [u8]) -> Self

Carries MAC command options in the frame header.

Arguments

• fopts - the frame options, up to 15 bytes.

Returns

The downlink, for chaining.
