Constructs a new basic_spanstream.
1) Uses the storage referenced by s as initial underlying buffer of the wrapped std::basic_spanbuf device. The wrapped std::basic_spanbuf object is constructed as basic_spanbuf<Char, Traits>(s, mode).
2) Move constructor. Move constructs the std::basic_iostream base subobject and the wrapped std::basic_spanbuf from those of rhs, and then calls set_rdbuf with the address of the wrapped std::basic_spanbuf in *this to install it.
3) Copy constructor is deleted.
basic_spanstream is not copyable.Parameters
| s | - | std::span referencing the storage to be use as initial underlying buffer of stream | ||||||||||||||||
| mode | - | specifies stream open mode. Following constants and bit-wise OR between them may be used:
| ||||||||||||||||
| other | - | another basic_spanstream to be moved from
|
Exceptions
May throw implementation-defined exceptions.
