moq_rtc/client/mod.rs
1//! HTTP-client side: dial a remote WHIP/WHEP endpoint over an SDP exchange.
2//!
3//! Counterpart to [`crate::server`]. Whereas the server accepts POSTed
4//! offers, the client mints the offer with `str0m::Rtc::sdp_api` and POSTs
5//! it to the remote URL. Once the answer arrives the same internal session
6//! driver takes over, so the per-codec bridges and UDP socket loop are shared.
