flat_static_buffer

A DynamicBuffer with a fixed size internal buffer using no memory allocations.

Synopsis

Defined in header <boost/beast/core/flat_static_buffer.hpp>

template<
    std::size_t N>
class flat_static_buffer :
    public flat_static_buffer_base

Types

Name	Description
const_buffers_type	The ConstBufferSequence used to represent the readable bytes.
mutable_buffers_type	The MutableBufferSequence used to represent the writable bytes.

Member Functions

Name	Description
base	Returns the `flat_static_buffer_base` portion of this object.
capacity	Return the maximum sum of input and output sizes that can be held without an allocation.
cdata	Returns a constant buffer sequence representing the readable bytes.
clear	Clear the readable and writable bytes to zero.
commit	Append writable bytes to the readable bytes.
consume	Remove bytes from beginning of the readable bytes.
data	Returns a constant buffer sequence representing the readable bytes. — Returns a mutable buffer sequence representing the readable bytes.
flat_static_buffer [constructor]	Constructor.
max_size	Return the maximum sum of the input and output sequence sizes.
operator=	Assignment.
prepare	Returns a mutable buffer sequence representing writable bytes.
size	Returns the number of readable bytes.

Protected Member Functions

Name	Description
reset	Reset the pointed-to buffer.

Description

Buffer sequences representing the readable and writable bytes, returned by data and prepare, will have a type of net::const_buffer or net::mutable_buffer.

Template Parameters

Type	Description
`N`	The number of bytes in the internal buffer.

Remarks

To reduce the number of template instantiations when passing objects of this type in a deduced context, the signature of the receiving function should use flat_static_buffer_base instead.
