Struct AnalysisHandler 

pub struct AnalysisHandler;

Implementations

impl AnalysisHandler

pub fn analyze_file<T: DeserializeOwned + TrackAnalyzable>( file_path: &Path, threshold: usize, ) -> Result<TrackStats, Box<dyn Error>>

Analyze tracks from a JSON file

Arguments

• file_path - Path to the JSON file containing track data
• threshold - Minimum play count threshold. Tracks with fewer plays than this value will be counted separately. For example, use 5 to identify tracks played less than 5 times.

Errors

• std::io::Error - If there was an error reading the file
• serde_json::Error - If the JSON cannot be parsed

Returns

• Result<TrackStats, Box<dyn std::error::Error>> - Analysis results

pub fn analyze_tracks<T: TrackAnalyzable>( tracks: &[T], threshold: usize, ) -> TrackStats

Analyze a vector of tracks

Arguments

• tracks - Vector of tracks to analyze (must implement TrackAnalyzable)
• threshold - Minimum play count threshold. Tracks with fewer plays than this value will be counted separately. For example, use 5 to identify tracks played less than 5 times.

Returns

• TrackStats - Analysis results containing play counts, most played tracks, and threshold-based groupings

pub fn print_analysis(stats: &TrackStats)

Print analysis results in a formatted way

Arguments

• stats - TrackStats to print

pub fn get_most_recent_timestamp<T: DeserializeOwned + Timestamped>( file_path: &Path, ) -> Result<Option<i64>>

Get the most recent timestamp from a JSON file.

Arguments

• file_path - Path to the JSON file

Errors

• std::io::Error - If the file cannot be opened or read
• LastFmError::Io - If the file cannot be opened
• LastFmError::Parse - If the JSON cannot be deserialized

Returns

• Option<i64> - Most recent timestamp
