Documentation

Overview

Package model provides type aliases for backward compatibility. All core analysis types have been migrated to the perflib/model package. This file ensures existing code that imports pkg/model continues to work.

Package model defines output data abstractions for different analysis types. Core analysis types have been migrated to github.com/junjiewwang/perf-analysis/perflib/model. This file retains only the AnalysisMode function that uses fmt (not migrated to avoid breaking the original function signature which differs from perflib's AnalysisModeString).

Package model defines the core data structures used throughout the application.
