A flexible context management library that provides a trait-based approach for handling
key-value data with support for multiple serialization formats.
## Features
- Generic context management through the `Contextualize` trait and a `Context` struct
- Support for multiple serialization formats (with feature flags):
- JSON (feature: "json")
- TOML (feature: "toml")
- YAML (feature: "yaml")
- Type-safe error handling with the `cdumay_core::Error` struct
## Example Usage
```rust
use std::collections::BTreeMap;
use serde::{Serialize, Deserialize};
use cdumay_context::{Contextualize, Context};
// Basic usage
let mut ctx = Context::new();
ctx.insert("name".to_string(), serde_value::Value::String("Alice".to_string()));
```
## Error Handling
The library provides a comprehensive error handling system through the `Error` enum:
```rust
use cdumay_context::{Context, ContextDump, Contextualize, UnExpectedError};
use rand::Rng;
use serde::{Serialize, Deserialize};
use std::collections::BTreeMap;
fn example_error_handling() -> cdumay_core::Result<()> {
let mut rng = rand::rng();
let dice_roll: u8 = rng.random_range(1..=6);
let mut ctx = Context::new();
ctx.insert("env".to_string(), serde_value::Value::String("prod".to_string()));
// Generic error
if dice_roll == 7 {
return Err(UnExpectedError::new().with_message("Something went wrong".to_string()).with_details(ctx.dump()).into());
}
Ok(())
}
```
