Crate rtcom_core 

Core library for rtcom — Rust Terminal Communication.

At v0.1 this crate provides:

• SerialDevice — async serial-port abstraction (Issue #2).
• SerialPortDevice — default backend built on tokio_serial.
• SerialConfig and companion enums — the framing and flow parameters.
• Event and EventBus — cross-task event hub (Issue #5).
• Session — the orchestrator that drives serial I/O against the bus.
• Error / Result — the crate-wide error type.

Later issues layer the event bus, session orchestrator, mappers, and command state machine on top of this foundation. See CLAUDE.md §7 for the full v0.1 plan.

Example

use rtcom_core::{SerialConfig, SerialDevice, SerialPortDevice};
use tokio::io::AsyncWriteExt;

let mut port = SerialPortDevice::open("/dev/ttyUSB0", SerialConfig::default())?;
port.write_all(b"hello\r\n").await?;
