Trait FieldValue 

pub trait FieldValue {
    // Required methods
    fn inspect(&self) -> Inspected;
    fn db_value(&self) -> DbValue;
}

A value that can be validated. Implemented for strings, numbers, bool, Option<T> and Vec<T>.

Required Methods

fn inspect(&self) -> Inspected

What rules see of the value.

fn db_value(&self) -> DbValue

The value as a query parameter, for unique and exists.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
