Trait ArgFromValue 

pub trait ArgFromValue<'k>: Sealed {
    type Output;

    // Required method
    fn from_value(value: &'k Value) -> TeraResult<Self::Output>;
}

Converts a template Value into a type that can be used in Rust code

Required Associated Types

type Output

Required Methods

fn from_value(value: &'k Value) -> TeraResult<Self::Output>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
