A collection of standard error types and error kinds commonly used in Rust applications.
This crate provides predefined error types and kinds using the `cdumay_core` framework.
### Features
- Common error types for IO operations and unexpected errors
- Easy integration with the `cdumay_core` framework
### Examples
```rust
use cdumay_error_standard::{FileNotExists, Unexpected};
use std::path::Path;
use cdumay_core::Result;
// Creating a FileNotExists error
fn check_file(path: &Path) -> Result<()> {
if !path.exists() {
return Result::Err(FileNotExists::new().with_message(format!(
"File {} does not exist",
path.display()
)).into());
}
Result::Ok(())
}
// Using Unexpected error for runtime errors
// Note: We use From<std::result::Result> to return cdumay_core::Result
fn divide(a: i32, b: i32) -> Result<i32> {
if b == 0 {
return Err(Unexpected::new().with_message("Division by zero".into()).into()).into();
}
Ok(a / b).into()
}
```
### Error Handling
All errors implement the `Into<Error>`, providing consistent error handling across your application:
```rust
use cdumay_error_standard::FileRead;
use cdumay_core::Result;
fn read_content() -> Result<String> {
let err = FileRead::new().with_message("Failed to read config file".into());
// Access error properties
println!("Error code: {}", err.code());
println!("Message: {}", err.message());
Result::Err(err.into())
}
```
