The output encoder type that wraps a buffer for writing binary data

create () creates a new output encoder with a fresh buffer

of_buffer buffer creates an output encoder from an existing buffer

contents t returns the string contents of the encoder's buffer

to_bytes t returns the byte contents of the encoder's buffer

zigzag32 n encodes a signed integer using zigzag encoding. Zigzag encoding maps signed integers to unsigned integers so that numbers with small absolute values have small encoded values.

zigzag64 n encodes a signed 64-bit integer using zigzag encoding. Zigzag encoding maps signed integers to unsigned integers so that numbers with small absolute values have small encoded values.

write_long t n writes a 64-bit integer to the encoder using variable-length encoding with zigzag encoding for signed values

write_int t n writes an integer to the encoder using variable-length encoding with zigzag encoding for signed values

write_null t () writes a null value (no-op in binary encoding)

write_boolean t b writes a boolean value as a single byte

write_float t f writes a 32-bit floating point value in little-endian byte order

write_double t f writes a 64-bit floating point value in little-endian byte order

write_bytes t bytes writes a byte sequence with length prefix

write_string t str writes a string with length prefix

write_fixed t bytes writes fixed-length bytes without a length prefix
