    pub version_ranges: Vec<(usize, usize)>,
    pub versions: InternedVersionManifest,
}

Struct-of-Arrays representation of the package manifest with interned strings.

This structure builds upon the PackageManifest format by adding string interning to further reduce memory usage and improve serialization efficiency. Repeated strings like author names, categories, and URLs are stored once in the interner and referenced by integer keys throughout the structure.

String interning is particularly beneficial for the Valheim mod ecosystem where the same authors maintain multiple packages and common patterns appear frequently in metadata.

Implementations

impl InternedPackageManifest

pub fn len(&self) -> usize

Returns the number of packages in the manifest.

pub fn is_empty(&self) -> bool

Returns true if the manifest contains no packages.

pub fn resolve_name_at(&self, idx: usize) -> Option<String>

Resolves the package name at the given index from the string interner.

Returns

The resolved string if a name exists at the index, otherwise None.

pub fn resolve_full_name_at(&self, idx: usize) -> Option<String>

Resolves the full package name at the given index from the string interner.

Returns

The resolved string if a full name exists at the index, otherwise None.

pub fn resolve_owner_at(&self, idx: usize) -> Option<String>

Resolves the package owner at the given index from the string interner.

Returns

The resolved string if an owner exists at the index, otherwise None.

pub fn get_package_by_full_name(&self, full_name: &str) -> Option<Package>

Retrieves a package by its full name.

Parameters

• full_name - The full name of the package to find

Returns

The package if found, otherwise None.

pub fn find_index_by_full_name(&self, full_name: &str) -> Option<usize>

Finds the index of a package by its full name.

Parameters

• full_name - The full name to search for

Returns

The index of the package if found, otherwise None.

pub fn get_package_at(&self, idx: usize) -> Package

Reconstructs a Package struct from the manifest data at the given index.

This method resolves all interned strings and constructs a complete Package with all its versions.

Parameters

• idx - The index of the package in the manifest

Returns

A fully materialized Package struct.

pub fn get_latest_version_at(&self, idx: usize) -> Option<usize>

Returns the index of the latest version for a package.

The latest version is determined by comparing the date_created field of all versions.

Parameters

• idx - The index of the package in the manifest

Returns

The index of the latest version, or None if the package has no versions.

pub fn build_name_index(&self) -> HashMap<String, usize>

Builds an index mapping full package names to their indices.

This is useful for fast lookups of packages by name.

Returns

A HashMap mapping resolved full names to package indices.

pub fn validate(&self) -> Result<(), String>

Validates the internal consistency of the manifest structure.

Checks that all parallel vectors have matching lengths and that version ranges are valid.

Returns

Ok if the manifest is valid, otherwise an error describing the problem.
