Struct UdsFlowControlFrame 

pub struct UdsFlowControlFrame {
    pub flag: u8,
    pub block_size: u8,
    pub separation_time: u8,
    pub padding: Vec<u8>,
}

Represents a UDS Flow Control Frame. This frame is sent by the receiver to control the flow of multi-frame transmissions.

Fields

flag: u8

Flow control flag:

• 0x00 = Continue to send (CTS)
• 0x01 = Wait (WT)
• 0x02 = Overflow/abort (OVFLW)

block_size: u8

The number of Consecutive Frames the sender can transmit before waiting.

separation_time: u8

Minimum separation time (ST) in milliseconds between transmitted frames.

padding: Vec<u8>

Optional padding bytes (if required for 8-byte CAN frames).

Implementations

impl UdsFlowControlFrame

pub fn new( flag: u8, block_size: u8, separation_time: u8, padding: Vec<u8>, ) -> Result<Self, FrameError>

Creates a new UDS Flow Control Frame.

Parameters:

• flag: Flow control flag (0=CTS, 1=Wait, 2=Overflow).
• block_size: Number of consecutive frames before next flow control.
• separation_time: Time delay (in ms) between frames.
• padding: Optional padding data (max 5 bytes).

Returns:

• Ok(UdsFlowControlFrame): If the padding size is valid.
• Err(FrameError): If the padding exceeds 5 bytes.

pub fn to_vec(&self) -> Result<Vec<u8>, DiagError>

Converts the flow control frame into a CAN frame byte vector.

Returns:

• Ok(Vec<u8>): The CAN frame representation.

Trait Implementations

impl Clone for UdsFlowControlFrame

fn clone(&self) -> UdsFlowControlFrame

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UdsFlowControlFrame

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

Formats the value using the given formatter.

impl PartialEq for UdsFlowControlFrame

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