Methods

Append<T>(ref T, Byte*, Int32)

Appends bytes to this string.

Declaration

public static FormatError Append<T>(this ref T fs, byte *utf8Bytes, int utf8BytesLength)
    where T : struct, INativeList<byte>, IUTF8Bytes

Parameters

Type	Name	Description
T	fs	The destination string.

Remarks

Similar to StringBuilder.AppendFormat but with significant limitations:

• Only supports numeric format placeholders of the form {0} .. {N}.
• No format modifiers (e.g. {0:x}) are supported.

The overloads of this method take up to ten strings to interpolate into the format string.
