This structure defines the following callbacks:

- `ucl_emitter_append_character` - a function that is called to append `nchars` characters equal to `c`
- `ucl_emitter_append_len` - used to append a string of length `len` starting from pointer `str`
- `ucl_emitter_append_int` - this function applies to integer numbers
- `ucl_emitter_append_double` - this function is intended to output floating point variable

The set of these functions could be used to output text formats of `UCL` objects to different structures or streams.

Libucl provides the following functions for emitting UCL objects:
