Struct CommandKeyParser 

pub struct CommandKeyParser { /* private fields */ }

State machine that splits stdin bytes into “data to send” vs. “commands to dispatch” using the configurable escape key.

Implementations

impl CommandKeyParser

pub const fn new(escape: u8) -> Self

Builds a parser whose command key is escape (commonly ^T = 0x14).

pub const fn escape_byte(&self) -> u8

Returns the escape byte this parser was configured with.

pub fn feed(&mut self, byte: u8) -> ParseOutput

Feed a single input byte; returns whatever the parser decided to emit for it.

State transitions (with ^T as the escape byte for illustration):

from \ byte	^T	Esc (0x1b)	mapped command	b	digit (in baud sub-state)	\r / \n (in baud sub-state)	other
Default	→ AwaitingCommand	→ Data(byte)	→ Data(byte)	→ Data(byte)	n/a	n/a	→ Data(byte)
AwaitingCommand	→ Data(^T)	→ Default	→ Command(…)	→ AwaitingBaudDigits	n/a	n/a	→ Default (drop)
AwaitingBaudDigits	→ Default (drop)	→ Default	→ Default (drop)	→ Default (drop)	append, stay	→ SetBaud / Default	→ Default (drop)

Trait Implementations

impl Default for CommandKeyParser

fn default() -> Self

Creates a parser whose escape byte is DEFAULT_ESCAPE_BYTE (^A / 0x01).
