Hoverbear · web-flow · commit f49d4bdf9946 · 2021-02-13T20:49:10.000+01:00
This is particularly handy when combined with `clap::value_t`. Here's demo of it working with Clap: ```bash cargo +stable init --bin tonic-demo cd tonic-demo cat <<-EOF >> Cargo.toml clap = "*" tonic = { path = "../hyperium/tonic/tonic" } EOF cat <<-EOF > src/main.rs use clap::{value_t, App, Arg}; use tonic::transport::Endpoint; fn main() { let matches = App::new("tonic-demo") .arg(Arg::with_name("host")) .get_matches(); let x = value_t!(matches.value_of("host"), Endpoint); println!("{:?}", x); } EOF cargo +stable run -- https://127.0.0.1:443 ``` Signed-off-by: Ana Hobden <operator@hoverbear.org>
