Implementations

impl Command

pub fn to_byte(self) -> u8

Converts a Command to its byte representation

Returns:

• u8: The byte representation of the command.

pub fn from_byte(cmd: u8) -> Result<Self, ProtocolError>

Convert a command byte to a Command enum variant

Arguments:

• cmd: The command byte to convert.

Returns:

• Ok(Command): If the command byte is recognized.
• Err(ProtocolError::Command): If the command byte is not recognized.

pub fn remaining_bytes(&self) -> Result<(usize, bool), ProtocolError>

Determine how many more bytes to read for this command type

Returns:

• Ok((usize, bool)): The number of bytes needed and whether the command will receive additional data (i.e. is a bulk command).
• Err(SwdError::Api): If the command is not recognized.

pub fn var_bytes(&self, count: u16) -> Result<usize, ProtocolError>

Determines how many variable bytes this command requires

Arguments:

• count: The number of words to read for bulk commands.

Returns:

• Ok(usize): The number of bytes to read for the command.
• Err(SwdError::Api): If the command is not recognized or if the count is invalid.

Trait Implementations

impl Clone for Command

fn clone(&self) -> Command

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Command

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

Formats the value using the given formatter.

impl Display for Command

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

Formats the value using the given formatter.

impl PartialEq for Command

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