Implementations
impl Message
[src]
pub fn matches(&mut self, other: &Message) -> bool
[src]
Matches this message with another. Used to validate requests with responses.
pub fn get_write_value_at_address(&self, address: &u16) -> Option<u16>
[src]
Gets the register/coil/input value at the given address, if it has been modified in the transaction. Returns the value as Some(u16) if it is found, otherwise returns None. The address passed in must be offset by 1 to reflect the actual coil/register and not the address found in the PDU. See the protocol reference for more information on addresses.
pub fn get_address_range(&self) -> Option<RangeInclusive<u16>>
[src]
Gets the address and quantity in the read/write data. If the data does not match and they can't be found, None is returned. The range returned is offset by 1 to account to reflect the coils/registers that start at 1 instead of in the PDU numbers where they start at 0. More details can be found in the protocol reference
