Struct StyleRegistry 

pub struct StyleRegistry { /* private fields */ }

Registry that tracks all scoped styles in the application. Uses &’static str to avoid runtime allocations - all CSS is embedded at compile time.

Implementations

impl StyleRegistry

pub fn new() -> Self

Creates a new empty style registry.

pub fn register(&mut self, hash: &'static str, css: &'static str)

Registers a scoped style with its hash.

Arguments

• hash - The unique hash/scope for this style (compile-time static)
• css - The scoped CSS content (compile-time static)

pub fn get_all_styles(&mut self) -> &str

Gets all registered styles as a single CSS string. Uses cached output for repeated calls (optimization #1).

pub fn contains(&self, hash: &str) -> bool

Checks if a style hash is already registered.

pub fn clear(&mut self)

Clears all registered styles (useful for testing).

pub fn len(&self) -> usize

Gets the number of registered styles.

Checks if the registry is empty.
