Detailed Description

Class representing a tag by storing the characters in a member array.

This never allocates, and is trivially default constructible and trivially copyable.

Note that trivially default constructible implies that a default-constructed object is uninitialized, so it is in an invalid state rather than a valid empty tag.

Constructor & Destructor Documentation

Tag_trivial() [1/2]

mysql::gtids::Tag_trivial::Tag_trivial ( )

defaultnoexcept

Default constructor: This does not initialize the tag! Use Tag unless you need std::is_trivially_default_constructible.

Tag_trivial() [2/2]

mysql::gtids::Tag_trivial::Tag_trivial ( const Is_tag auto &  other )

inlineexplicitnoexcept

Copy from any other tag.

Member Function Documentation

data()

const char * mysql::gtids::Tag_trivial::data ( ) const

inline

Return a const pointer to the data.

out_str()

auto mysql::gtids::Tag_trivial::out_str ( )

inlineprivate

Return an Output String Wrapper writing to this Tag.

size()

std::size_t mysql::gtids::Tag_trivial::size ( ) const

inline

Return the number of characters of the tag: an integer between 0 and max_size.

throwing_make()

static auto mysql::gtids::Tag_trivial::throwing_make ( const std::string_view &  sv )

inlinestatic

Return a new Tag, initialized with the given string.

Use in exception-free code only if the tag format has been validated already.

Parameters

sv	string_view to copy from.

Exceptions

std::domain_error

if sv does not have the correct tag format.
