im recieving the following error when i try to use the anchor_lang create:

[Error - 8:41:25 PM] Request textDocument/inlayHint failed. Message: request handler panicked: mismatched kinds in substitution Code: -32603

code snippet to reproduce:

    let payer = Keypair::new();
    let client = Client::new(Cluster::Mainnet, Rc::new(payer));

    // Create program
    let program = client.program(alphazero_chain_swap::ID).unwrap();
    let instructions: Vec<Instruction> = program.request()
        .accounts(accounts)
        .args(args)
        .instructions()
        .unwrap();

The Error happens when i try after the args(args) parameter to use .instructions()

[SupaGoku]

Getting exactly the same issue. If I comment out the .instructions(), the error goes away.

[Veykril]

Note that the snippets is useless to us without the other relevant code for it

[SupaGoku]

Here's a minimum example:

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

[dependencies]
anchor-client = { version = "0.29.0", features = ["async"] }

use std::{ str::FromStr, sync::Arc };

use anchor_client::{ solana_sdk::{ pubkey::Pubkey, signature::Keypair }, Client, Cluster };

fn main() {
  let program_pubkey = Pubkey::from_str("FooBar").unwrap();
  let http_url = "FooBar".into();
  let ws_url = "FooBar".into();
  let cluster = Cluster::Custom(http_url, ws_url);

  let payer = Keypair::new();

  let client = Client::new(cluster, Arc::new(payer));
  let program = client.program(program_pubkey).unwrap();

  let instructions = program.request().accounts(accounts).args(args).instruction();
}

accounts and args are undefined, which gives an error, but that doesn't matter. The panic still happens in rust-analyzer console/output.

[SupaGoku]

I can confirm that the issue started with version 0.3.2029.

@SiyahKara Install version 0.3.2020 for a temporary workaround.

[ShoyuVanilla]

Here's a minimum example:

Where can I get accounts and args in the last line? And the last method is instructions(), maybe?

[SupaGoku]

Here you go:

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

[dependencies]
anchor-client = { version = "0.29.0", features = ["async"] }
raydium-amm-v3 = { git = "https://github.com/raydium-io/raydium-clmm.git" }

use std::{ str::FromStr, sync::Arc };

use anchor_client::{ solana_sdk::{ instruction::AccountMeta, pubkey::Pubkey, signature::Keypair }, Client, Cluster };

fn main() {
  let program_pubkey = Pubkey::from_str("FooBar").unwrap();
  let http_url = "FooBar".into();
  let ws_url = "FooBar".into();
  let cluster = Cluster::Custom(http_url, ws_url);

  let payer = Keypair::new();

  let client = Client::new(cluster, Arc::new(payer));
  let program = client.program(program_pubkey).unwrap();

  let accounts = vec![AccountMeta {
    pubkey: Pubkey::from_str("FooBar").unwrap(),
    is_signer: false,
    is_writable: false,
  }];

  let args = raydium_amm_v3::instruction::Swap {
    amount: 1,
    other_amount_threshold: 1,
    sqrt_price_limit_x64: 1,
    is_base_input: true,
  };

  let instructions = program.request().accounts(accounts).args(args).instructions();
}

[ShoyuVanilla]

Thanks! I'll try with your example code

[ShoyuVanilla]

Good news: I just made an minimal, reproducible example;

use core::ops::Deref;

struct Struct<'a, T>(&'a T)

trait Trait {}

impl<'a, T: Deref<Target = impl Trait>> Struct<'a, T> {
    fn foo(&self) {
    }

    fn bar(&self) {
        let _ = self.foo();
    }
}

and I think that I can fix this soon 😄

[SiyahKara]

works like a charm thank you guys you are amazing
