Crate leptos_macro

Macros for use with the Leptos framework.

Macros

include_view

This behaves like the view macro, but loads the view from an external file instead of parsing it inline.

memo

Generates a memo into a struct with a default getter.

slice

Generates a slice into a struct with a default getter and setter.

template

The template macro behaves like view, except that it wraps the entire tree in a ViewTemplate. This optimizes creation speed by rendering most of the view into a <template> tag with HTML rendered at compile time, then hydrating it. In exchange, there is a small binary size overhead.

view

The view macro uses RSX (like JSX, but Rust!) It follows most of the same rules as HTML, with the following differences:

Attribute Macros

component

Annotates a function so that it can be used with your template as a Leptos <Component/>.

island

Defines a component as an interactive island when you are using the islands feature of Leptos. Apart from the macro name, the API is the same as the component macro.

lazy

The #[lazy] macro marks an async function as a function that can be lazy-loaded from a separate (WebAssembly) binary.

server

Declares that a function is a server function. This means that its body will only run on the server, i.e., when the ssr feature on this crate is enabled.

slot

Annotates a struct so that it can be used with your Component as a slot.

Derive Macros

Params

Derives a trait that parses a map of string keys and values into a typed data structure, e.g., for route params.
