Trait oso::FromPolar

source · [−]
pub trait FromPolar: Clone {
    fn from_polar(val: PolarValue) -> Result<Self>;
}
Expand description

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
