Struct freya::prelude::Template

pub struct Template {
    pub name: &'static str,
    pub roots: &'static [TemplateNode],
    pub node_paths: &'static [&'static [u8]],
    pub attr_paths: &'static [&'static [u8]],
}
Expand description

A static layout of a UI tree that describes a set of dynamic and static nodes.

This is the core innovation in Dioxus. Most UIs are made of static nodes, yet participate in diffing like any dynamic node. This struct can be created at compile time. It promises that its name is unique, allow Dioxus to use its static description of the UI to skip immediately to the dynamic nodes during diffing.

For this to work properly, the Template::name must be unique across your entire project. This can be done via variety of ways, with the suggested approach being the unique code location (file, line, col, etc).

Fields§

§name: &'static str

The name of the template. This must be unique across your entire program for template diffing to work properly

If two templates have the same name, it’s likely that Dioxus will panic when diffing.

§roots: &'static [TemplateNode]

The list of template nodes that make up the template

Unlike react, calls to rsx! can have multiple roots. This list supports that paradigm.

§node_paths: &'static [&'static [u8]]

The paths of each node relative to the root of the template.

These will be one segment shorter than the path sent to the renderer since those paths are relative to the topmost element, not the roots field.

§attr_paths: &'static [&'static [u8]]

The paths of each dynamic attribute relative to the root of the template

These will be one segment shorter than the path sent to the renderer since those paths are relative to the topmost element, not the roots field.

Implementations§

§

impl Template

pub fn is_completely_dynamic(&self) -> bool

Is this template worth caching at all, since it’s completely runtime?

There’s no point in saving templates that are completely dynamic, since they’ll be recreated every time anyway.
