Struct openthread_sys::otCoapTxParameters

#[repr(C)]
pub struct otCoapTxParameters {
    pub mAckTimeout: u32,
    pub mAckRandomFactorNumerator: u8,
    pub mAckRandomFactorDenominator: u8,
    pub mMaxRetransmit: u8,
}

Represents the CoAP transmission parameters.

@note mAckTimeout * ((2 ** (mMaxRetransmit + 1)) - 1) * (mAckRandomFactorNumerator / mAckRandomFactorDenominator) must not exceed what can be represented by a uint32_t (0xffffffff). This limitation allows OpenThread to avoid 64-bit arithmetic.

Fields

mAckTimeout: u32

Minimum spacing before first retransmission when ACK is not received, in milliseconds (RFC7252 default value is 2000ms).

mAckRandomFactorNumerator: u8

Numerator of ACK_RANDOM_FACTOR used to calculate maximum spacing before first retransmission when ACK is not received (RFC7252 default value of ACK_RANDOM_FACTOR is 1.5; must not be decreased below 1).

mAckRandomFactorDenominator: u8

Denominator of ACK_RANDOM_FACTOR used to calculate maximum spacing before first retransmission when ACK is not received (RFC7252 default value of ACK_RANDOM_FACTOR is 1.5; must not be decreased below 1).

mMaxRetransmit: u8

Maximum number of retransmissions for CoAP Confirmable messages (RFC7252 default value is 4).
