Interface Writer

Available returns how many bytes are unused in the buffer.

AvailableBuffer returns an empty buffer with b.Available() capacity. This buffer is intended to be appended to and passed to an immediately succeeding [Writer.Write] call. The buffer is only valid until the next write operation on b.

Buffered returns the number of bytes that have been written into the current buffer.

Flush writes any buffered data to the underlying [io.Writer].

ReadFrom implements [io.ReaderFrom]. If the underlying writer supports the ReadFrom method, this calls the underlying ReadFrom. If there is buffered data and an underlying ReadFrom, this fills the buffer and writes it before calling ReadFrom.

Reset discards any unflushed buffered data, clears any error, and resets b to write its output to w. Calling Reset on the zero value of [Writer] initializes the internal buffer to the default size. Calling w.Reset(w) (that is, resetting a [Writer] to itself) does nothing.

Size returns the size of the underlying buffer in bytes.

Write writes the contents of p into the buffer. It returns the number of bytes written. If nn < len(p), it also returns an error explaining why the write is short.

WriteByte writes a single byte.

WriteRune writes a single Unicode code point, returning the number of bytes written and any error.

WriteString writes a string. It returns the number of bytes written. If the count is less than len(s), it also returns an error explaining why the write is short.
