Struct read_write_ext::ReadWriteChain
source · [−]Expand description
A wrapper for a pair of structs, R and RW.
Implements std::io::Read
. Reads from R
until it is empty, then reads from RW
.
Implements std::io::Write
. Passes all writes through to RW
.
This is like std::io::Chain
that also passes through writes.
