Trait TemplateProperty 

pub trait TemplateProperty {
    type Output;

    // Required method
    fn extract(&self) -> Result<Self::Output, TemplatePropertyError>;
}

Lazily evaluated value which can fail to evaluate.

Required Associated Types

type Output

Required Methods

fn extract(&self) -> Result<Self::Output, TemplatePropertyError>

Dyn Compatibility

This trait is dyn compatible.

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