[−][src]Enum postcard_cobs::DecoderState

pub enum DecoderState {
    Idle,
    Grab(u8),
    GrabChain(u8),
}

The DecoderState is used to track the current state of a streaming decoder. This struct does not contain the output buffer (or a reference to one), and can be used when streaming the decoded output to a custom data type.

Variants

Idle

State machine has not received any non-zero bytes

Grab(u8)

1-254 bytes, can be header or 00

GrabChain(u8)

255 bytes, will be a header next

Methods

impl DecoderState[src]

pub fn feed(&mut self, data: u8) -> Result<DecodeResult, ()>[src]

Push a single encoded byte into the state machine. If the input was unexpected, such as an early end of a framed message segment, an Error will be returned, and the current associated output buffer contents should be discarded.

If a complete message is indicated, the decoding state machine will automatically reset itself to the Idle state, and may be used to begin decoding another message.

NOTE: Sentinel value must be included in the input to this function for the decoding to complete
