- src/doc-manager.ts:334-361 (handler)Core handler function that verifies documentation is built, retrieves the cached doc path, and reads the main index.html content as markdown using RustdocUrl.readContent.public async getCrateDoc(projectPath: string, crateName: string): Promise<string> { const isBuilt = await this.checkDoc(projectPath, crateName); if (!isBuilt) { throw new DocError( DocErrorCode.BUILD_FAILED, 'Failed to build documentation' ); } const cached = await this.cache.get(projectPath, crateName); if (!cached) { throw new DocError( DocErrorCode.CACHE_ERROR, 'Cache error: Documentation entry not found' ); } try { const { docPath } = cached; return await RustdocUrl.readContent(docPath); } catch (error) { throw new DocError( DocErrorCode.SEARCH_FAILED, 'Failed to read crate documentation', error ); } }
