Trait TemplateEngine 

pub trait TemplateEngine {
    type Error: IntoResponse;

    // Required method
    fn render<S: Serialize>(
        &self,
        key: &str,
        data: S,
    ) -> Result<String, Self::Error>;
}

An abstraction over different templating engines

Implementing custom engines

#[derive(Debug)]
pub struct CustomEngine;

impl TemplateEngine for CustomEngine {
    type Error = Infallible;   
    fn render<S: Serialize>(&self, key: &str, data: S) -> Result<String, Self::Error> {
        /* Render your template and return the result */
        let result = "Hello world".into();
        Ok(result)    
    }
}

See the full working example custom_engine.rs

Required Associated Types

type Error: IntoResponse

Error type returned if the engine is unable to process the data

Required Methods

fn render<S: Serialize>( &self, key: &str, data: S, ) -> Result<String, Self::Error>

Renders the template defined by the given key using the Serializable data

Dyn Compatibility

This trait is not dyn compatible.

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