http::basic_parser::on_chunk_body_impl

http::basic_parser::on_chunk_body_impl

Called each time additional data is received representing part of a body chunk.

Synopsis

std::size_t
on_chunk_body_impl(
    std::uint64_t remain,
    string_view body,
    error_code& ec);

Description

This virtual function is invoked for each piece of the body which is received while parsing of a message. This function is only used when no chunked transfer encoding is present.

Parameters

Name	Description
`remain`	The number of bytes remaining in this chunk. This includes the contents of passed `body`. If this value is zero, then this represents the final chunk.
`body`	A string holding the additional body contents. This may contain nulls or unprintable characters.
`ec`	An output parameter which the function may set to indicate an error. The error will be clear before this function is invoked.

Return Value

This function should return the number of bytes actually consumed from the body value. Any bytes that are not consumed on this call will be presented in a subsequent call.
