Trait FromValue 

pub trait FromValue: Sized {
    // Required method
    fn from_value(value: Value) -> Result<Self>;
}

Trait for converting JSON values to Rust types. This enables automatic type inference in the ftool API.

Required Methods

fn from_value(value: Value) -> Result<Self>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
