std::time::Duration is an invalid type for "1 second"

[ghost]

Hi, I'm using hocon 0.4.0 and serde 1.0.124. The config file says blah = 1 second, the config struct says blah: std::time::Duration, and hocon says

Error: Error deserializing: "blah: invalid type for field \"blah\""

When I change the struct's field type from std::time::Duration to String, then the struct field successfully gets the textual value 1 second.

Am I doing something wrong please? I looked into Hocon's source code and it looks like std::time::Duration is supported.

PS. Hocon is the best config format ever, loved it since Scala times, thanks for your work.

Thanks you for reporting this!

Duration formats were supported in Hocon formats, but not all the way through deserialization... They now are (in 0.5.1), with an api inspired by humantime-serde

Either with an attribute:

hocon.rs/tests/deserialize.rs

Lines 129 to 133 in 0433e51

	#[derive(Deserialize, Debug)]
	struct Test {
	#[serde(deserialize_with = "Serde::<Duration>::with")]
	a: std::time::Duration,
	}

Or with a wrapper type:

hocon.rs/tests/deserialize.rs

Lines 113 to 116 in 0433e51

	#[derive(Deserialize, Debug)]
	struct Test {
	a: Serde<Duration>,
	}
