Description
The following code fails to compile:
#[async_trait]
pub trait AsCleanJson {
pub async fn clean_json<T: DeserializeOwned>(self) -> Result<T>;
}However, after observing start of the stacktrace I see the following message: pub not permitted here because it's implied,
after removing it, this code compiles fine:
#[async_trait]
pub trait AsCleanJson {
async fn clean_json<T: DeserializeOwned>(self) -> Result<T>;
}The depencencies used:
anyhow = "1.0.68"
async-trait = "0.1.61"
reqwest = "0.11.13"
serde = { version = "1.0.152", features = ["serde_derive"] }
Here's the stacktrace:
error[E0449]: unnecessary visibility qualifier
--> src/deserialization.rs:8:5

8 | pub async fn clean_json<T: DeserializeOwned>(self) -> Result<T>;
| ^^^ `pub` not permitted here because it's implied

= note: `async` trait functions are not currently supported
= note: consider using the `async-trait` crate: https://crates.io/crates/async-trait
= note: see issue #91611 <https://github.com/rust-lang/rust/issues/91611> for more information
