Trait FromHostValue 

pub trait FromHostValue: Sized {
    // Required methods
    fn from_host_value(v: &Value) -> Self;
    fn host_type() -> HostType;
}

Extracts a Rust argument from a Value for a registered host closure.

Required Methods

fn from_host_value(v: &Value) -> Self

fn host_type() -> HostType
