Trait FromDynamic 

pub trait FromDynamic
where
    Self: Sized,
{
    // Required method
    fn from_dynamic(
        ctx: &NativeCallContext<'_>,
        v: Dynamic,
        default: Option<&Self>,
    ) -> Result<Self, Box<EvalAltResult>>;
}

Helper trait to go from a Rhai dynamic object to a particular type

Required Methods

fn from_dynamic( ctx: &NativeCallContext<'_>, v: Dynamic, default: Option<&Self>, ) -> Result<Self, Box<EvalAltResult>>

Build an object from a dynamic value and optional default

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.
