# span_validator
Simple validation with error reporting, inspired by [validator](https://github.com/Keats/validator). Provide users with targeted, actionable error messages.
## Why not validator?
I'd love to see this functionality [become a part of validator](https://github.com/Keats/validator/pull/272). Until then, unless you specifically need span-based validation, just use validator. This crate only exists to provide better error messages than possible with just validator.
## Example
```rust
use span_validator::email::{Error, ErrorSpan, validate_email};
// invalid"@example.com
//        ^
assert_eq!(
    validate_email(r#"invalid"@example.com"#),
    Err(ErrorSpan { error_type: Error::InvalidUserCharacter, span: 7..7 })
);
```
