Functions ¶
func FindCsvRecordStart ¶
func FindCsvRecordStart(buffer SplitBuffer, start int, expectNRecords int) int
FindCsvRecordStart finds the next closest possible starting position of a CSV record in the buffer. It starts searching from the starting index to find the next unquoted newline character under two scenarios:
- Assuming the search starts within quotes.
- Assuming the search starts outside of quotes.
For each of the found newline positions, it attempts to parse the subsequent data as CSV records, expecting a specified number of records that all share the same number of fields. If a valid starting position is found where the expected number of records can be parsed correctly, it returns that position. If no valid starting position is found, it returns -1.
func FindNextUnquotedNewline ¶
func FindNextUnquotedNewline(buffer SplitBuffer, start int) [2]int
FindNextUnquotedNewline finds the next unquoted newline character in the buffer starting from the given index. It returns two indices:
- The index assuming the search starts within quotes.
- The index assuming the search starts outside of quotes.
Types ¶
type SplitBuffer ¶
type SplitBuffer []byte
SplitBuffer is a byte slice with helper methods for parsing CSV data.
func (SplitBuffer) Eof ¶
func (b SplitBuffer) Eof(at int) bool
Eof checks if the given index is at or beyond the end of the buffer.
func (SplitBuffer) Equals ¶
func (b SplitBuffer) Equals(at int, r ...rune) bool
Equals checks if the buffer matches one or more runes starting at the given index.
func (SplitBuffer) FindClosingQuote ¶
func (b SplitBuffer) FindClosingQuote(start int) int
FindClosingQuote finds the index of the next possible closing quote starting from the given index. That is, it finds the next non-double quote character. It returns -1 if no closing quote is found.
func (SplitBuffer) IsEscapedQuote ¶
func (b SplitBuffer) IsEscapedQuote(at int) bool
IsEscapedQuote checks if the given index is an escaped quote (two consecutive double quotes).
func (SplitBuffer) IsNewline ¶
func (b SplitBuffer) IsNewline(at int) bool
IsNewline checks if the given index is a newline character or sequence.
func (SplitBuffer) IsQuote ¶
func (b SplitBuffer) IsQuote(at int) bool
IsQuote checks if the given index is a quote character.
func (SplitBuffer) NextIndexOf ¶
func (b SplitBuffer) NextIndexOf(r rune, start int) int
NextIndexOf returns the index of the next occurrence of the given rune starting from the specified index.
