ConstBufferSequence

A constant buffer sequence represents zero or more contiguous memory regions as a bidirectional range whose value type is convertible to const_buffer.

Related Identifiers

const_buffer, is_const_buffer_sequence, begin, end

Requirements

T denotes a type meeting the requirements of ConstBufferSequence.
t denotes a (possibly const) value of type T.
u denotes an identifier.
It is the type decltype(buffers::begin(t)).

Expression Type Semantics, Pre/Post-conditions

Expression	Type	Semantics, Pre/Post-conditions
`std::iterator_traits<It>::value_type`		Convertible to `const_buffer`.
`It`		Requirements `requires std::bidirectional_iterator<It>`
`begin(t)`	`It`	Returns an iterator to the first element of the sequence.
`end(t)`	`It`	Returns an iterator one past the last element of the sequence.
