Trait oso::FromPolar[−][src]

pub trait FromPolar: Clone {
    fn from_polar(val: PolarValue) -> Result<Self>;
}

Convert Polar types to Rust types.

This trait is automatically implemented for any type that implements the PolarClass trait, which should be preferred.

This is also implemented automatically using the #[derive(PolarClass)] macro.

Trait bounds

FromPolar requires Clone because we can only get a borrowed value back from oso. In the future, this could be updated to return borrowed data instead.

The default implementation for PolarClass also requires types to be Send + Sync, since it is possible to store a FromPolar value on an Oso instance which can be shared between threads
