A small crate to manipulate base64 data.
### Features
- Maps all variants of `base64::DecodeError` into structured `cdumay_core::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_core`.
- Provides convenient macro for error conversion
### Usage
Using the `Base64DecodeErrorConverter` directly:
```rust
use base64::{engine::general_purpose, Engine as _};
use std::collections::BTreeMap;
use cdumay_core::{ErrorConverter, Error};
use cdumay_base64::Base64DecodeErrorConverter;
fn decode_base64(input: &str) -> cdumay_core::Result<Vec<u8>> {
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)
})
}
```
Using the `convert_decode_result!` macro:
```rust
use base64::{engine::general_purpose, Engine as _};
use cdumay_core::{ErrorConverter, Error};
use std::collections::BTreeMap;
use cdumay_base64::convert_decode_result;
fn decode_base64(input: &str) -> cdumay_core::Result<Vec<u8>> {
let mut context = BTreeMap::new();
context.insert("input".to_string(), serde_value::Value::String(input.to_string()));
convert_decode_result!(general_purpose::STANDARD.decode(input), context, "Failed to decode base64")
}
```
