Struct Parser 

pub struct Parser { /* private fields */ }

Accumulates bytes from a link and emits complete frames.

Feed bytes with push_byte; each call returns a Frame on the byte that completes one. Resolving a message id to its CRC_EXTRA is left to the caller, so the parser works against any dialect.

Implementations

impl Parser

pub fn new() -> Self

Creates an empty parser.

Returns

A parser with nothing buffered.

pub fn push_byte<F>(&mut self, byte: u8, crc_extra_for: &F) -> Option<Frame>

where F: Fn(u32) -> Option<u8>,

Feeds one byte, returning a frame if this byte completes a valid one.

A frame whose checksum fails, or whose message id crc_extra_for does not recognize, is discarded and the parser resynchronizes on the next start marker.

Arguments

• byte - the next byte from the link.
• crc_extra_for - resolves a message id to its CRC_EXTRA, or None if unknown.

Returns

The completed frame, or None if more bytes are needed.

Trait Implementations

impl Clone for Parser

fn clone(&self) -> Parser

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for Parser

fn default() -> Self

Returns the “default value” for a type.
