tcspc::input_stream Concept Reference

Description

Concept that is satisfied when T conforms to the libtcspc input stream interface.

Determines whether T is move-constructible and provides the noexcept member functions is_error(), is_eof(), is_good(), tell(), skip(), and read() with the signatures and return types documented at Input streams.

Concept definition

template<typename T>
concept input_stream =
    std::move_constructible<T> &&
    requires(T &s, std::uint64_t bytes, std::span<std::byte> buf) {
        { s.is_error() } noexcept -> std::same_as<bool>;
        { s.is_eof() } noexcept -> std::same_as<bool>;
        { s.is_good() } noexcept -> std::same_as<bool>;
        { s.tell() } noexcept -> std::same_as<std::optional<std::uint64_t>>;
        { s.skip(bytes) } noexcept -> std::same_as<bool>;
        { s.read(buf) } noexcept -> std::same_as<std::uint64_t>;
    }
