Trait Validate 

pub trait Validate {
    // Required method
    fn validate(&self) -> Result<(), ValidationError>;
}

Types that can validate their own fields.

Implement this trait on request structs and call validate() inside your handler before processing the input. Use ? to propagate the ValidationError as a crate::Error (HTTP 422).

Example

use modo::validate::{Validate, ValidationError, Validator};

struct SignUp {
    username: String,
}

impl Validate for SignUp {
    fn validate(&self) -> Result<(), ValidationError> {
        Validator::new()
            .field("username", &self.username, |f| f.required().min_length(3))
            .check()
    }
}

Required Methods

fn validate(&self) -> Result<(), ValidationError>

Validate this value, returning all field-level errors at once.

Errors

Returns ValidationError containing every failing field and its error messages when one or more fields are invalid.
