Struct ImplementationProvider 

pub struct ImplementationProvider { /* private fields */ }

Provider for finding implementations of types and interfaces in Perl code

This provider locates implementations and inheritance relationships in Perl codebases:

• Subclasses that inherit from a base class using @ISA or use parent
• Overridden methods in derived classes
• Package implementations and blessed type relationships

LSP Workflow Integration

Integrates with the Parse → Index → Navigate → Complete → Analyze workflow:

• Parse: AST analysis identifies package and method definitions
• Index: Workspace indexing tracks inheritance relationships
• Navigate: Provides go-to-implementation functionality
• Complete: No direct integration (implementations don’t affect completion)
• Analyze: Implementation analysis supports refactoring decisions

Performance

• Implementation finding: <100ms for typical inheritance hierarchies
• Memory usage: <5MB for implementation metadata
• Workspace indexing: Leverages cached inheritance relationships

Implementations

impl ImplementationProvider

pub fn new( workspace_index: Option<Arc<WorkspaceIndex>>, ) -> ImplementationProvider

Create a new implementation provider with optional workspace indexing

Arguments

• workspace_index - Optional workspace index for cross-file inheritance tracking

Returns

A new ImplementationProvider configured for finding Perl implementations

Examples

use perl_lsp_rs_core::providers::navigation::ImplementationProvider;

// Without workspace indexing (single-file analysis)
let provider = ImplementationProvider::new(None);

// With workspace indexing (cross-file inheritance)
let provider = ImplementationProvider::new(Some(workspace_index));

pub fn find_implementations( &self, ast: &Node, line: u32, character: u32, uri: &str, documents: &HashMap<String, String>, ) -> Vec<LocationLink>

Find implementations at the given position
