Enum Message 

pub enum Message {
    GetInfo,
    SetTck {
        period_ns: u32,
    },
    Shift {
        num_bits: u32,
        tms: Box<[u8]>,
        tdi: Box<[u8]>,
    },
}

A Message is transfered from the client to the server. For each message, the client is expected to send the message and wait for a response from the server. The server needs to process each message in the order received and promptly provide a response. For the XVC 1.0 protocol, only one connection is assumed.

Variants

GetInfo

Requests info from the server. This is used to determine protocol capabilities of the server.

SetTck

Configures the TCK period. When sending JTAG vectors the TCK rate may need to be varied to accomodate cable and board signal integrity conditions. This command is used by clients to adjust the TCK rate in order to slow down or speed up the shifting of JTAG vectors.

Fields

period_ns: u32

Shift

Used to shift JTAG vectors in-and out of a device.

Fields

num_bits: u32

represents the number of TCK clk toggles needed to shift the vectors out

tms: Box<[u8]>

a byte sized vector with all the TMS data. The vector is num_bits and rounds up to the nearest byte.

tdi: Box<[u8]>

a byte sized vector with all the TDI data. The vector is num_bits and rounds up to the nearest byte.

Implementations

impl Message

pub fn from_reader( reader: &mut impl Read, max_shift_bytes: usize, ) -> Result<Message, ReadError>

pub fn write_to(&self, writer: &mut impl Write) -> Result<()>

Trait Implementations

impl Clone for Message

fn clone(&self) -> Message

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Message

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

Formats the value using the given formatter.

impl PartialEq for Message

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

impl Eq for Message

impl StructuralPartialEq for Message
