[−][src]Function sensirion_hdlc::decode

pub fn decode(
    input: &[u8], 
    s_chars: SpecialChars
) -> Result<ArrayVec<[u8; 1024]>, HDLCError>

Produces unescaped (decoded) message without FEND characters.

Inputs

  • Vec: A vector of the bytes you want to decode
  • SpecialChars: The special characters you want to swap

Output

  • Result<ArrayVec<u8;1024>>: Decoded output message

Error

  • HDLCError::TooMuchDecodedData: More than expected 260 bytes of decoded data
  • HDLCError::FendCharInData: Checks to make sure the full decoded message is the full length. Found the SpecialChars::fend inside the message.
  • HDLCError::MissingTradeChar: Checks to make sure every frame escape character fesc is followed by either a tfend or a tfesc.
  • HDLCError::MissingFirstFend: Input vector is missing a first SpecialChars::fend
  • HDLCError::MissingFinalFend: Input vector is missing a final SpecialChars::fend
  • HDLCError::TooFewData: Data to decode is fewer than 4 bytes`
  • HDLCError::TooMuchData: Data to decode is larger than 1000 bytes`

Example

extern crate sensirion_hdlc;
let chars = sensirion_hdlc::SpecialChars::default();
let input =[ 0x7E, 0x01, 0x50, 0x00, 0x00, 0x00, 0x05, 0x80, 0x09, 0x7E];
let op_vec = sensirion_hdlc::decode(&input.to_vec(), chars);
