expected tuple struct or tuple variant, found struct variant KbKey::Character #2403
Description
When I was using druid version 0.7.0, the code worked fine.
[dependencies]
druid = "0.7.0"
reqwest = { version = "0.11", features = ["blocking"] }
serde = { version = "1.0", features = ["derive"] }
serde_json = "1.0"
But when I modify my 0.8.3, I get an error that has nothing to do with my code, as follows
I tried the following operations, and it still didn’t solve the problem after re-running it.
# problem not solved
cargo clean
# problem not solved
rm -rf ~/.cargo/registry/src/index.crates.io-6f17d22bba15001f/druid-shell-0.8.3
Thanks ~
run command
cargo run --bin radio

let radio = RadioGroup::new(choices).lens(AppData::choice);
let label = Label::new(|data: &AppData, _env: &druid::Env| {
