Struct ThemeRegistry 

pub struct ThemeRegistry { /* private fields */ }

A registry holding all loaded themes.

This is a pure data structure - no I/O operations. Use ThemeLoader to create and populate a registry.

Themes are keyed by their unique ThemeInfo::key (typically a repository URL or pack/name path). Lookups fall back to matching by display name for backward compatibility with configs that store just e.g. "dark".

Implementations

impl ThemeRegistry

pub fn get(&self, key_or_name: &str) -> Option<&Theme>

Look up a theme by key or name.

Tries exact key match first, then falls back to matching by normalized display name (for backward compat with configs that just say "dark").

pub fn get_cloned(&self, key_or_name: &str) -> Option<Theme>

Get a cloned theme by key or name.

pub fn resolve_key<'a>(&'a self, key_or_name: &'a str) -> Option<&'a str>

Resolve a key-or-name to the canonical registry key.

pub fn list(&self) -> &[ThemeInfo]

List all available themes with metadata.

pub fn names(&self) -> Vec<String>

Get all theme display names.

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

Check if a theme exists (by key or name).

pub fn len(&self) -> usize

Number of themes in the registry.

pub fn is_empty(&self) -> bool

Check if registry is empty.

pub fn to_json_map(&self) -> HashMap<String, Value>

Convert all themes to a JSON map (key → serde_json::Value).

Keyed by the unique registry key. Each value is the theme data with added _key and _pack metadata fields so plugins can distinguish themes and show display names.
