Struct BebobAvc

pub struct BebobAvc(/* private fields */);

The implementation of AV/C transaction with quirks specific to BeBoB solution.

It seems a unique quirk that the status code in response frame for some AV/C commands is against AV/C general specification in control operation.

Implementations

impl BebobAvc

pub fn bind(&self, node: &impl IsA<FwNode>) -> Result<(), Error>

pub fn control<O: AvcOp + AvcControl>( &self, addr: &AvcAddr, op: &mut O, timeout_ms: u32, ) -> Result<(), Error>

pub fn status<O: AvcOp + AvcStatus>( &self, addr: &AvcAddr, op: &mut O, timeout_ms: u32, ) -> Result<(), Error>

Trait Implementations

impl Debug for BebobAvc

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

Formats the value using the given formatter.

impl Default for BebobAvc

fn default() -> BebobAvc

Returns the “default value” for a type.

impl Ta1394Avc<Error> for BebobAvc

fn transaction( &self, command_frame: &[u8], timeout_ms: u32, ) -> Result<Vec<u8>, Error>

Transmit given command frame and return received response frame.

fn control<O: AvcOp + AvcControl>( &self, addr: &AvcAddr, op: &mut O, timeout_ms: u32, ) -> Result<(), Ta1394AvcError<Error>>

const FRAME_SIZE: usize = 512usize

The maximum size of frame in both command and response.

const RESP_CODE_MASK: u8 = 15u8

The mask for first byte of response frame to detect status code. The rest bits express Command/transaction set (CTS) but appears not to be used actually.

fn compose_command_frame( ctype: AvcCmdType, addr: &AvcAddr, opcode: u8, operands: &[u8], ) -> Result<Vec<u8>, Ta1394AvcError<T>>

fn detect_response_operands<'a>( frame: &'a [u8], addr: &AvcAddr, opcode: u8, ) -> Result<(AvcRespCode, &'a [u8]), AvcRespParseError>

fn status<O>( &self, addr: &AvcAddr, op: &mut O, timeout_ms: u32, ) -> Result<(), Ta1394AvcError<T>>

where O: AvcOp + AvcStatus,

fn specific_inquiry<O>( &self, addr: &AvcAddr, op: &mut O, timeout_ms: u32, ) -> Result<(), Ta1394AvcError<T>>

where O: AvcOp + AvcControl,

fn notify<O>( &self, addr: &AvcAddr, op: &mut O, timeout_ms: u32, ) -> Result<(), Ta1394AvcError<T>>

where O: AvcOp + AvcNotify,
