Detailed Description

template<Field_size field_size>
struct mysql::serialization::Byte_count_helper< field_size >

Structure that contains methods to count the number of bytes needed to encode a specific field.

Template Parameters

field_size

The number of bytes requested by the user. 0 means "default". For string, field_size is the boundary length of the string

Member Function Documentation

count_write_bytes() [1/2]

template<Field_size field_size>

static size_t mysql::serialization::Byte_count_helper< field_size >::count_write_bytes ( const std::string &  arg )

inlinestatic

Calculates bytes needed to encode the bounded string field (specialization of count_write_bytes for string type)

Parameters

arg	String argument needed to be encoded

Returns

Bytes needed to encode the arg

count_write_bytes() [2/2]

template<Field_size field_size>

template<class Type , typename Enabler = std::enable_if_t< std::is_integral<std::decay_t<Type>>::value>>

static size_t mysql::serialization::Byte_count_helper< field_size >::count_write_bytes ( const Type &  )

inlinestatic

Calculates bytes needed to encode the field.

Template Parameters

Type	of the field, as represented in the code

Returns

Bytes needed to encode the field
