func Average ¶

func Average[T Number](values ...T) T

func CountRunes ¶

func CountRunes(slice []rune, target rune) int

func Equal ¶

func Equal[X, Y any](x X, y Y) bool

func FindLine ¶

func FindLine[T ~int, B []rune | []byte | string](content B, index T) int

FindLine returns the line number (1-based) for a given index within the content. The function accepts content as string, []rune, or []byte and determines the line number by counting newline characters ('\n') that appear before the specified index.

Generic Parameters:

• T: integer numeric type for the index (constrained to integer types)
• B: content type, constrained to []rune, []byte, or string

Parameters:

• content: the content to analyze (string, []rune, or []byte)
• index: position in the content for which to determine the line number

Returns:

• int: line number (starting from 1) corresponding to the index
• returns -1 if the index is out of range (negative or greater than content length)

Example usage:

text := "Line 1\nLine 2\nLine 3"
lineNum := FindLine(text, 10) // Returns 2, as index 10 is on the second line

The function internally handles different content types:

• For strings: uses strings.Count to count '\n' occurrences
• For []rune: uses an auxiliary CountRunes function
• For []byte: uses bytes.Count to count '\n' occurrences

Implementation notes:

• The function uses a type assertion to determine the content type at runtime
• Counts the number of newline characters ('\n') before the given index
• Returns line number starting from 1
• Returns -1 if the index is out of bounds (negative or exceeding content length)

Edge cases:

• If the content is empty or the index is out of range, the function returns -1.

func FindLineFromReader ¶

func FindLineFromReader[T ~int](r *bytes.Reader, index T) int
