Serializer

General programmable serialization functions. (A shared interface to various reading/writing to/from different inputs/outputs)

#include <serializer.h>

Serializer Structure (struct serializer)

.. type:: struct serializer

.. member:: void     *serializer.data

.. member:: size_t   (*serializer.read)(void *, void *, size_t)

.. member:: size_t   (*serializer.write)(void *, const void *, size_t)

.. member:: int64_t  (*serializer.seek)(void *, int64_t, enum serialize_seek_type)

.. member:: int64_t  (*serializer.get_pos)(void *)

Serializer Inline Functions

.. function:: size_t s_read(struct serializer *s, void *data, size_t size)


.. function:: size_t s_write(struct serializer *s, const void *data, size_t size)


.. function:: size_t serialize(struct serializer *s, void *data, size_t len)


.. function:: int64_t serializer_seek(struct serializer *s, int64_t offset, enum serialize_seek_type seek_type)


.. function:: int64_t serializer_get_pos(struct serializer *s)


.. function:: void s_w8(struct serializer *s, uint8_t u8)


.. function:: void s_wl16(struct serializer *s, uint16_t u16)


.. function:: void s_wl32(struct serializer *s, uint32_t u32)


.. function:: void s_wl64(struct serializer *s, uint64_t u64)


.. function:: void s_wlf(struct serializer *s, float f)


.. function:: void s_wld(struct serializer *s, double d)


.. function:: void s_wb16(struct serializer *s, uint16_t u16)


.. function:: void s_wb24(struct serializer *s, uint32_t u24)


.. function:: void s_wb32(struct serializer *s, uint32_t u32)


.. function:: void s_wb64(struct serializer *s, uint64_t u64)


.. function:: void s_wbf(struct serializer *s, float f)


.. function:: void s_wbd(struct serializer *s, double d)

Array Output Serializer

Provides an output serializer used with dynamic arrays.

#include <util/array-serializer.h>

Array Output Serializer Structure (struct array_output_data)

.. type:: struct array_output_data


.. member:: DARRAY(uint8_t) array_output_data.bytes

Array Output Serializer Functions

.. function:: void array_output_serializer_init(struct serializer *s, struct array_output_data *data)


.. function:: void array_output_serializer_free(struct array_output_data *data)

File Input/Output Serializers

Provides file reading/writing serializers.

#include <util/file-serializer.h>

File Input Serializer Functions

.. function:: bool file_input_serializer_init(struct serializer *s, const char *path)

   Initializes a file input serializer.

   :return:     *true* if file opened successfully, *false* otherwise


.. function:: void file_input_serializer_free(struct serializer *s)

   Frees a file input serializer.

File Output Serializer Functions

.. function:: bool file_output_serializer_init(struct serializer *s, const char *path)

   Initializes a file output serializer.

   :return:     *true* if file created successfully, *false* otherwise


.. function:: bool file_output_serializer_init_safe(struct serializer *s, const char *path, const char *temp_ext)

   Initializes and safely writes to a temporary file (determined by the
   temporary extension) until freed.

   :return:     *true* if file created successfully, *false* otherwise


.. function:: void file_output_serializer_free(struct serializer *s)

   Frees the file output serializer and saves the file.
