Types ¶

type Boundary ¶

type Boundary struct {
	Offset int     // Location as a byte offset in the source file.
	Start  bool    // Is this the start of a block?
	Count  int     // Event count from the cover profile.
	Norm   float64 // Count normalized to [0..1].
	Index  int     // Order in input file.
}

Boundary represents the position in a source file of the beginning or end of a block as reported by the coverage profile. In HTML mode, it will correspond to the opening or closing of a <span> tag and will be used to colorize the source

type Profile ¶

type Profile struct {
	FileName string
	Mode     string
	Blocks   []ProfileBlock
}

Profile represents the profiling data for a specific file.

func ParseProfiles ¶

func ParseProfiles(fileName string) ([]*Profile, error)

ParseProfiles parses profile data in the specified file and returns a Profile for each source file described therein.

func ParseProfilesFromReader ¶

func ParseProfilesFromReader(rd io.Reader) ([]*Profile, error)

ParseProfilesFromReader parses profile data from the Reader and returns a Profile for each source file described therein.

func (*Profile) Boundaries ¶

func (p *Profile) Boundaries(src []byte) (boundaries []Boundary)

Boundaries returns a Profile as a set of Boundary objects within the provided src.

type ProfileBlock ¶

type ProfileBlock struct {
	StartLine, StartCol int
	EndLine, EndCol     int
	NumStmt, Count      int
}

ProfileBlock represents a single block of profiling data.
