|
//! Sailfish is a simple, small, and extremely fast template engine for Rust.
|
|
|
|
//! Before reading this reference,
|
|
|
|
//! I recommend reading [User guide](https://sailfish.netlify.app/en/).
|
|
|
|
//!
|
|
|
|
//! This crate contains utilities for rendering sailfish template.
|
|
|
|
//! If you want to use sailfish templates, import `sailfish-macros` crate and use
|
|
|
|
//! derive macro `#[derive(TemplateOnce)]` or `#[derive(Template)]`.
|
|
|
|
//!
|
|
|
|
//! In most cases you don't need to care about the `runtime` module in this crate, but
|
|
|
|
//! if you want to render custom data inside templates, you must implement
|
|
|
|
//! `runtime::Render` trait for that type.
|
|
|
|
//!
|
|
|
|
//! ```ignore
|
|
|
|
//! #[macro_use]
|
|
|
|
//! extern crate sailfish_macros;
|
|
|
|
//!
|
|
|
|
//! use sailfish::TemplateOnce;
|
|
|
|
//!
|
|
|
|
//! #[derive(TemplateOnce)]
|
|
|
|
//! #[template(path = "hello.stpl")]
|
|
|
|
//! struct HelloTemplate {
|
|
|
|
//! messages: Vec<String>
|
|
|
|
//! }
|
|
|
|
//!
|
|
|
|
//! fn main() {
|
|
|
|
//! let ctx = HelloTemplate {
|
|
|
|
//! messages: vec!["foo".to_string(), "bar".to_string()]
|
|
|
|
//! };
|
|
|
|
//!
|
|
|
|
//! println!("{}", ctx.render_once().unwrap());
|
|
|
|
//! }
|
|
|
|
//! ```
