Functions ¶
func AssertOneRow ¶
func BytesToString ¶
BytesToString converts byte slice to string.
func CamelCased ¶
func RetryBackoff ¶
Retry backoff with jitter sleep to prevent overloaded conditions during intervals https://www.awsarchitectureblog.com/2015/03/backoff.html
func StringToBytes ¶
StringToBytes converts string to byte slice.
func ToExported ¶
func Underscore ¶
Underscore converts "CamelCasedString" to "camel_cased_string".
func UpperString ¶
Types ¶
type BufReader ¶
type BufReader struct {
Columns [][]byte
// contains filtered or unexported fields
}
func NewBufReader ¶
func (*BufReader) Buffered ¶
Buffered returns the number of bytes that can be read from the current buffer.
func (*BufReader) BytesReader ¶
func (b *BufReader) BytesReader(n int) *BytesReader
func (*BufReader) Discard ¶
Discard skips the next n bytes, returning the number of bytes discarded.
If Discard skips fewer than n bytes, it also returns an error. If 0 <= n <= b.Buffered(), Discard is guaranteed to succeed without reading from the underlying io.BufReader.
func (*BufReader) ReadFullTemp ¶
func (*BufReader) ReadSlice ¶
ReadSlice reads until the first occurrence of delim in the input, returning a slice pointing at the bytes in the buffer. The bytes stop being valid at the next read. If ReadSlice encounters an error before finding a delimiter, it returns all the data in the buffer and the error itself (often io.EOF). ReadSlice fails with error ErrBufferFull if the buffer fills without a delim. Because the data returned from ReadSlice will be overwritten by the next I/O operation, most clients should use ReadBytes or ReadString instead. ReadSlice returns err != nil if and only if line does not end in delim.
func (*BufReader) SetAvailable ¶
func (*BufReader) UnreadByte ¶
type BytesReader ¶
type BytesReader struct {
// contains filtered or unexported fields

func (*BytesReader) ReadFullTemp ¶
func (r *BytesReader) ReadFullTemp() ([]byte, error)
func (*BytesReader) Reset ¶
func (r *BytesReader) Reset(b []byte)
func (*BytesReader) UnreadByte ¶
func (r *BytesReader) UnreadByte() error
type PGError ¶

// contains filtered or unexported fields
}
func NewPGError ¶
