Trait FromValue

pub trait FromValue: Sized {
    // Required method
    fn from_value(value: Value, mv8: &MiniV8) -> Result<Self>;
}

Trait for types convertible from Value.

Required Methods

fn from_value(value: Value, mv8: &MiniV8) -> Result<Self>

Performs the conversion.

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.
