Function decode 

pub fn decode(frame: &[u8], output: &mut [u8]) -> Result<usize, SerialError>

Decodes a single SLIP frame, recovering the original payload.

A leading END (RFC 1055’s flush byte) and any empty run before the payload are skipped; decoding stops at the END that closes the frame, or at the end of the slice if it carries no trailing delimiter.

Arguments

• frame - the framed bytes, with or without the trailing END.
• output - the buffer the payload is written into; it never needs more room than frame.

Returns

The number of payload bytes written to output.

Errors

Returns SerialError::InvalidEscape if an ESC is followed by an unexpected byte, SerialError::TruncatedFrame if the frame ends in the middle of an escape sequence, and SerialError::BufferTooSmall if output cannot hold the payload.

Examples

use pamoja_serial::slip::{self, END};

let mut payload = [0u8; 4];
// A leading END is tolerated and the trailing one closes the frame.
let n = slip::decode(&[END, b'h', b'i', END], &mut payload)?;
assert_eq!(&payload[..n], b"hi");
