Expand description

Structure provides an abstraction for cluster with CASR reports

Fields§

§number: usize

Cluster number

Implementations§

source§

impl Cluster

source

pub fn new( number: usize, paths: Vec<PathBuf>, stacktraces: Vec<Stacktrace>, crashlines: Vec<String> ) -> Self

Create new Cluster

source

pub fn paths(&self) -> &Vec<PathBuf>

Get CASR report paths

source

pub fn stacktraces(&self) -> &Vec<Stacktrace>

Get CASR report stactraces

source

pub fn cluster_reports( reports: &[ReportInfo], offset: usize, dedup: bool ) -> Result<(HashMap<usize, Cluster>, usize, usize)>

Perform CASR reports clustering

§Arguments

  • reports - slice of ReportInfo

  • offset - cluster enumerate offset

  • dedup - deduplicate crashline, if true

§Return value
  • HashMap of Cluster with cluster number as key
  • Number of valid casreps before crashline deduplication
  • Number of valid casreps after crashline deduplication
source

pub fn insert( &mut self, path: PathBuf, stacktrace: Stacktrace, crashline: String, dedup: bool ) -> bool

Add new CASR report to cluster

§Arguments

  • stacktrace - new CASR report stacktrace

  • crashline - new CASR report crashline

  • dedup - deduplicate crashline, if true

§Return value

true if new CASR report may be added, false if report is duplicate of someone else

source

pub fn diam(&mut self) -> f64

Get cluster diameter

source

pub fn relation(&mut self, new: &Stacktrace) -> Relation

Get “relation” between new report and specified cluster

§Arguments
  • new - new report stacktrace
§Return value

Relation enum with proximity measure according specified strategy

source

pub fn dist(cluster1: &Cluster, cluster2: &Cluster) -> f64

Get complete distance between clusters NOTE: Result also can be interpreted as diameter of cluster merge result

source

pub fn dist_rep(cluster: &Cluster, report: &ReportInfo) -> f64

Get complete distance between cluster and report NOTE: Result also can be interpreted as diameter of cluster merge result
