Raw Blame History

//! Parameter types and enums.
//!
//! This module contains various helper types.
//!
//! # Primtive Parameter Wrappers and Enumeration
//!
//! This module includes wrapper for primitive rust types using the newtype pattern.
//! This was also done for pairs and triplets of these primitive types.
//! The [WritableToBeBytes] was implemented for all those types as well, which allows to easily
//! convert them into a network friendly raw byte format. The [ParamsRaw] enumeration groups
//! all newtypes and implements the [WritableToBeBytes] trait itself.
//!
//! ## Example for primitive type wrapper
//!
//! ```
//! use satrs::params::{ParamsRaw, ToBeBytes, U32Pair, WritableToBeBytes};
//!
//! let u32_pair = U32Pair(0x1010, 25);
//! assert_eq!(u32_pair.0, 0x1010);
//! assert_eq!(u32_pair.1, 25);
//! // Convert to raw stream
//! let raw_buf = u32_pair.to_be_bytes();
//! assert_eq!(raw_buf, [0, 0, 0x10, 0x10, 0, 0, 0, 25]);
//!
//! // Convert to enum variant
//! let params_raw: ParamsRaw = u32_pair.into();
//! assert_eq!(params_raw, (0x1010_u32, 25_u32).into());
//!
//! // Convert to stream using the enum variant
//! let mut other_raw_buf: [u8; 8] = [0; 8];
//! params_raw.write_to_be_bytes(&mut other_raw_buf).expect("Writing parameter to buffer failed");
//! assert_eq!(other_raw_buf, [0, 0, 0x10, 0x10, 0, 0, 0, 25]);
//!
//! // Create a pair from a raw stream
//! let u32_pair_from_stream: U32Pair = raw_buf.as_slice().try_into().unwrap();
//! assert_eq!(u32_pair_from_stream.0, 0x1010);
//! assert_eq!(u32_pair_from_stream.1, 25);
//! ```
//!
//! # Generic Parameter Enumeration
//!
//! The module also contains generic parameter enumerations.
//! This includes the [ParamsHeapless] enumeration for contained values which do not require heap
//! allocation, and the [Params] which enumerates [ParamsHeapless] and some additional types which
//! require [alloc] support but allow for more flexbility.
