Function render 

pub fn render<T: Serialize>(
    name: &'static str,
    source: &'static str,
    surface: &Surface,
    content: &T,
) -> Result<String, Error>

Available on crate features surface-model and surface-templates only.

Render the template source, named name, in a fresh environment.

The template sees two variables: surface, the Surface, and content, the CLI’s own serializable context.

Errors

Returns minijinja’s Error when source does not compile, or when rendering fails, such as on a variable the strict environment does not define.
