Errors

A Rust library for handling string interpolation in error messages, with support for both named and positional placeholders.

Features

• Named Placeholders: Use {name} for named field interpolation
• Positional Placeholders: Use {} or {0}, {1}, etc. for positional arguments
• Format Specifiers: Supports all standard Rust format specifiers like :?, :x}, etc.
• Efficient: Uses BTreeSet for efficient identifier tracking
• No Panic: Gracefully handles malformed format strings

Usage

Add this to your Cargo.toml:

[dependencies]
errors = { git = "https://github.com/iamgabrielsoft/errors.git" }

use errors::parse_internal;

// Basic usage
let (formatted, identifiers) = parse_internal("Hello, {name}! You are {age} years old.");
println!("Formatted: {}", formatted);
println!("Identifiers: {:?}", identifiers);

// Positional placeholders
let (formatted, _) = parse_internal("Hello, {}! Your ID is {:04x}");
println!("{}", formatted); // "Hello, __0! Your ID is __1:04x"
