Sew

Sew is a Rust library that provides a constant-size string with various manipulation methods, along with other unique string types. It is designed to be used in no_std environments and offers features like serialization, random string generation, and more.

Features

• Constant-Size Strings: ConStr is a fixed-size character string structure that allows for efficient manipulation and querying.
• Infallible Strings: InfallibleString can represent both valid and invalid UTF-8 sequences, useful for handling arbitrary byte sequences.
• Pattern Searching: Implement custom pattern searching with the PatternSearcher trait, and more advanced modifications with the GetChar and GetSubStr traits.
• Macros: Easily create ConStr instances with the new_cstr! macro.
• Feature Flags:
  • serde: Enables serialization and deserialization support.
  • rand: Allows for random string generation.
  • expandable: Additional utilities for string manipulation.
  • unsafe_infallible: Provides unsafe mutable access to InfallibleString via DerefMut.

Installation

Add sew to your Cargo.toml:

[dependencies]
sew = { version = "0.7.7", features = ["full_unsafe"] }

Usage

Basic Usage

use sew::helpers::new_cstr;

fn main() {
    let x = new_cstr!("Hello, World!");
    println!("{}", x);
}

Features

Constant-Size Strings

ConStr provides a variety of methods for string manipulation:

• new(): Create a new ConStr initialized with NUL characters.
• len(): Get the length of the ConStr.
• insert(), remove(), replace(): Modify the string content.
• to_uppercase(), to_lowercase(): Change the case of the string.

Infallible Strings

InfallibleString can handle both valid and invalid UTF-8 sequences:

• new_valid(): Create a valid InfallibleString.
• new_invalid(): Create an invalid InfallibleString.
• push_str(), push_byte(): Append content to the string.

Pattern Searching

Implement the PatternSearcher trait to define custom pattern matching logic, or GetChar or GetSubStr for advanced modification logic.
