Futures-Util version issue

Question

My code was working fine until today I got the error

error: the 'rustc.exe' binary, normally provided by the 'rustc' component, is not applicable to the 'stable-x86_64-pc-windows-msvc' toolchain

I fixed it with rustup toolchain install stable

After that I am having dependency issue with futures-util.

My toml file is:

[package]
name = "rusting"
version = "0.1.0"
edition = "2021"

    # See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html
    
    [dependencies]
    rand = "0.8.5"
    
    schnorr_fun = "0.8.2"
    
    chrono = "0.4.24"
    
    tokio = { version = "1.27.0", features = ["full"] }
    
    futures = "0.3.28"
    
    schnorrkel = "0.10.2"
    
    serde_json = "1.0.95"

I am getting error (after running cargo run):

I can understand there's some dependancy clash. But I cant fix it. Maybe tokio also is using a future crate with a different dependency. Any help please.

Answer 1

I found the solution by myself.

First just try

cargo clean

followed by

cargo update

Then try cargo run

If it doesn't work, just restart your ide (for me vs code) and try cargo clean again.
