Struct Registry 

pub struct Registry {
    pub domains: HashMap<String, HashMap<String, Vec<u8>>>,
}

All data from a Content Pack, grouped by domain (from manifest.toml).

Registry is an “in-memory filesystem”. It does not know the structure of the data inside files. Each plugin decides how to parse the bytes it receives.

Structure

domains: {
    "items"   → { "items_edible.ron": [...bytes...], "items_material.ron": [...bytes...] },
    "recipes" → { "combinations.ron": [...bytes...] },
}

Fields

domains: HashMap<String, HashMap<String, Vec<u8>>>

Domain → { filename → raw bytes }

Implementations

impl Registry

pub fn new() -> Self

Create an empty Registry.

pub fn file(&self, domain: &str, filename: &str) -> Result<&[u8], String>

Get raw bytes of a specific file within a domain.

Returns an error message string if the domain or file is not found.

pub fn has_domain(&self, name: &str) -> bool

Check whether a domain exists.

pub fn is_empty(&self) -> bool

Whether the Registry is empty.

pub fn domain(&self, name: &str) -> Result<&HashMap<String, Vec<u8>>, String>

Get all files in a domain.

Returns an error message string if the domain does not exist.

pub fn add_file(&mut self, domain: &str, filename: &str, data: Vec<u8>)

Add a file to a domain.

pub fn domain_names(&self) -> impl Iterator<Item = &str>

Iterate over all domain names.

pub fn len(&self) -> usize

Number of domains.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Registry

fn fmt(&self, f: &mut Formatter<'_>) -> Result
