A small utility crate for converting `base64::DecodeError` into structured, typed errors using the [`cdumay_error`](https://docs.rs/cdumay-error/) framework. This allows consistent, meaningful error reporting with custom codes, messages, and additional context.

### Features

- Maps all variants of `base64::DecodeError` into structured `cdumay_error::Error` types.
- Provides unique error codes, HTTP status codes, and human-readable messages.
- Easily attach contextual metadata for better debugging.
- Simple integration into any Rust project using `base64` and `cdumay_error`.

### Usage

```rust
use base64::{engine::general_purpose, Engine as _};
use cdumay_error::ErrorConverter;
use std::collections::BTreeMap;
use cdumay_error_base64::Base64DecodeErrorConverter;

fn decode_base64(input: &str) -> Result<Vec<u8>, cdumay_error::Error> {
    general_purpose::STANDARD.decode(input).map_err(|e| {
        let mut context = BTreeMap::new();
        context.insert("input".to_string(), serde_value::Value::String(input.to_string()));
        Base64DecodeErrorConverter::convert(&e, "Failed to decode base64".to_string(), context)
    })
}
