typed inbound sermo stream view

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

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

main {
    const _ s ← call 'runtime:echo' ("salve")

    for from s.tuus<string>().cursor() const frame {
        assert frame.data ≡ "salve"
    }
}
