Struct AliasTable 

pub struct AliasTable { /* private fields */ }

Alias table for mapping package names across different conventions.

Implementations

impl AliasTable

pub fn new() -> Self

Create a new empty alias table

pub fn with_builtins() -> Self

Create an alias table with built-in common aliases.

The builtins map alternate spellings of the SAME package (import name vs distribution name, underscore vs hyphen variants) — never related but distinct packages. Entries here merge at high confidence in the diff, so a wrong entry hides a real component change; related packages (react/react-dom, webpack/webpack-cli) must NOT be aliased, and cross-ecosystem equivalence belongs in [CrossEcosystemDb] (crate::matching::CrossEcosystemDb), which applies a penalty and is gated per config.

The table is opt-in: FuzzyMatcher starts with an empty table; install this one via FuzzyMatcher::with_alias_table.

pub fn add_aliases(&mut self, canonical: &str, aliases: &[&str])

Add aliases for a canonical package

pub fn is_empty(&self) -> bool

Check whether the table has any entries at all.

pub fn get_canonical(&self, alias: &str) -> Option<String>

Get the canonical name for an alias

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

Check if a name is an alias of a canonical name

pub fn get_aliases(&self, canonical: &str) -> Option<&HashSet<String>>

Get all aliases for a canonical name

pub fn load_json(&mut self, json: &str) -> Result<(), Error>

Load aliases from JSON

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

Export aliases to JSON
