Struct Component 

pub struct Component {
    pub name: String,
    pub props: Vec<String>,
    pub defaults: HashMap<String, String>,
    pub template: String,
}

A custom component definition

Fields

name: String

Component name (e.g., “what-card”, “what-modal”)

props: Vec<String>

Expected props

defaults: HashMap<String, String>

Default values for props

template: String

Template content

Implementations

impl Component

pub fn from_file(path: impl AsRef<Path>) -> Result<Self>

Load a component from an HTML template file (legacy format with wrapper tag)

pub fn from_file_with_name(path: impl AsRef<Path>) -> Result<Self>

Load a component from a file, deriving the name from the filename

This is the new recommended format where:

• Filename becomes the component name: nav.html → nav
• Props and defaults are defined in a <what> block
• Template content is everything outside the <what> block

pub fn parse_with_name(content: &str, name: String) -> Result<Self>

Parse component content with a provided name (filename-based)

Supports both new <what> block format and legacy wrapper tag format.

pub fn parse(content: &str) -> Result<Self>

Parse a component definition from HTML template content (legacy format)

Expected format:

<component name="card" props="title, slug">
  <article class="card">
    <h3>#title#</h3>
    <slot/>
  </article>
</component>

pub fn render( &self, props: &HashMap<String, String>, children: Option<&str>, context: &HashMap<String, Value>, ) -> String

Render the component with given props and children

Priority order (highest to lowest):

1. Passed props (from usage)
2. Defaults (from component definition)
3. Empty string (for undeclared props)
