# AT Commands builder and parser for Rust #![no_std] [![crates.io](https://img.shields.io/crates/v/at-commands.svg)](https://crates.io/crates/at-commands) [![Documentation](https://docs.rs/at-commands/badge.svg)](https://docs.rs/at-commands)

This crate can be used to build and parse at command style messages efficiently.

Help would be appreciated! Interested in new features, efficiency improvements and API improvements.

## Usage

Builder:
```rust
use at_commands::builder::CommandBuilder;

let mut buffer = [0; 128];

// Make a query command
let result = CommandBuilder::create_query(&mut buffer, true)
    .named("+MYQUERY")
    .finish()
    .unwrap();

// Buffer now contains "AT+MYQUERY?"
// Copy or DMA the resulting slice to the device.

// Make a set command
let result = CommandBuilder::create_set(&mut buffer, false)
    .named("+MYSET")
    .with_int_parameter(42)
    .finish()
    .unwrap();

// Buffer now contains "+MYSET=42"
// Copy or DMA the resulting slice to the device.
```

Parser:
```rust
use at_commands::parser::CommandParser;

let (x, y, z) = CommandParser::parse(b"+SYSGPIOREAD:654,\"true\",-65154\r\nOK\r\n")
    .expect_identifier(b"+SYSGPIOREAD:")
    .expect_int_parameter()
    .expect_string_parameter()
    .expect_int_parameter()
    .expect_identifier(b"\r\nOK\r\n")
    .finish() 
    .unwrap();

// x = 654
// y = "true"
// z = -65154
```
