Description
Reproduction steps:
- enable serde in cargo.toml
[dependencies]
serde = "1.0"
serde_derive = "1.0"
serde_json = "1.0"
rclrs = "0.3"
rosidl_runtime_rs = "0.3"
std_msgs = "*"
nav_msgs = { version = "*", features = ["serde"] }
- serde json
let odom = nav_msgs::msg::Odometry::default();
let json_str = serde_json::to_string(&odom).unwrap();
colcon build
