typed inbound 通道 stream view

# =============================================================================
# 接收 — typed inbound 通道 stream view.
# =============================================================================
#
# What this teaches:
#   • Typed inbound stream — `s.tuus<T>()` creates a typed view over the
#     incoming frames of a 通道 connection
#   • Cursor consumption — 迭代器() yields frames that can be iterated with
#     `遍历 取自`
#
# Common mistakes:
#   • confusing 调用 route syntax — accessing `接收<T>` stream after `fini()` has been called leaves no usable data
#
# See also: 调用, 通道, 帧, 迭代器

# sermo.tuus<T>() — typed inbound frame stream

main {
    const 通道 s ← call 'runtime:echo' ("salve")
    for from s.tuus<string>().cursor() const frame {
        assert frame.data ≡ "salve"
    }
}
