Types ¶
type ExprStats ¶
type ExprStats struct {
ExprTimeNs int64 `json:"total_time_ns"`
NumEval int `json:"num_eval"`
NumRedo int `json:"num_redo"`
NumGenExpr int `json:"num_gen_expr"`
Location *ast.Location `json:"location"`
}
ExprStats represents the result of profiling an expression.
type ExprStatsAggregated ¶ added in v0.31.0
type ExprStatsAggregated struct {
ExprTimeNsStats interface{} `json:"total_time_ns_stats"`
NumEval int `json:"num_eval"`
NumRedo int `json:"num_redo"`
NumGenExpr int `json:"num_gen_expr"`
Location *ast.Location `json:"location"`
}
ExprStatsAggregated represents the result of profiling an expression by aggregating `n` profiles.
func AggregateProfiles ¶ added in v0.31.0
func AggregateProfiles(profiles ...[]ExprStats) []ExprStatsAggregated
type FileReport ¶
type FileReport struct {
Result []ExprStats `json:"result"`
}
FileReport represents a profiler report for a single file.
type Profiler ¶
type Profiler struct {
// contains filtered or unexported fields
}
Profiler computes and reports on the time spent on expressions.
func (*Profiler) Config ¶ added in v0.21.0
func (*Profiler) Config() topdown.TraceConfig
Config returns the standard Tracer configuration for the profiler
func (*Profiler) ReportByFile ¶
ReportByFile returns a profiler report for expressions grouped by the file name. For each file the results are sorted by increasing row number.
func (*Profiler) ReportTopNResults ¶
ReportTopNResults returns the top N results based on the given criteria. If N <= 0, all the results based on the criteria are returned.
func (*Profiler) TraceEvent ¶ added in v0.21.0
TraceEvent updates the coverage state.
type Report ¶
type Report struct {
Files map[string]*FileReport `json:"files"`
}
Report represents the profiler report for a set of files.
