Detailed Description

buffer that has string_view interface This class provides string_view interface. This class hold string_view target's lifetime optionally.

Constructor & Destructor Documentation

buffer() [1/3]

constexpr async_mqtt::buffer::buffer ( string_view sv )

inlineexplicitconstexpr

string_view constructor

Parameters

sv	string_view This constructor doesn't hold the sv target's lifetime. It behaves as string_view. Caller needs to manage the target lifetime.

buffer() [2/3]

async_mqtt::buffer::buffer ( std::string )

explicitdelete

string constructor (deleted)

Parameters

string

This constructor is intentionally deleted. Consider buffer(std::string("ABC")), the buffer points to dangling reference.

buffer() [3/3]

async_mqtt::buffer::buffer ( string_view sv, any life )

inline

string_view and lifetime constructor

Parameters

sv	string_view
sp	shared_ptr_array that holds sv target's lifetime If user creates buffer via this constructor, sp's lifetime is held by the buffer.

Member Function Documentation

substr() [1/2]

buffer async_mqtt::buffer::substr ( size_type pos = 0, size_type count = npos ) &&

inline

get substring The returned buffer ragnge is the same as string_view::substr(). In addition the lifetime is moved to returned buffer.

Parameters

offset	offset point of the buffer
length	length of the buffer, If the length is string_view::npos then the length is from offset to the end of string.

substr() [2/2]

buffer async_mqtt::buffer::substr ( size_type pos = 0, size_type count = npos ) const &

inline

get substring The returned buffer ragnge is the same as string_view::substr(). In addition the lifetime is shared between returned buffer and this buffer.

Parameters

offset	offset point of the buffer
length	length of the buffer, If the length is string_view::npos then the length is from offset to the end of string.
