	SourcePath string         // Search path for source files.
	TrimPath   string         // Paths to trim from source file paths.

	IntelSyntax bool // Whether or not to print assembly in Intel syntax.
}

Options are the formatting and filtering options used to generate a profile.

type Report

type Report struct {
	// contains filtered or unexported fields
}

Report contains the data and associated routines to extract a report from a profile.

func New

func New(prof *profile.Profile, o *Options) *Report

New builds a new report indexing the sample values interpreting the samples with the provided function.

func NewDefault

func NewDefault(prof *profile.Profile, options Options) *Report

NewDefault builds a new report indexing the last sample value available.

func (*Report) Total

func (rpt *Report) Total() int64

Total returns the total number of samples in a report.

type TextItem

type TextItem struct {
	Name                  string
	InlineLabel           string // Not empty if inlined
	Flat, Cum             int64  // Raw values
	FlatFormat, CumFormat string // Formatted values
}

TextItem holds a single text report entry.

func TextItems

func TextItems(rpt *Report) ([]TextItem, []string)

TextItems returns a list of text items from the report and a list of labels that describe the report.
