rust-analyzer.completion.callable.snippets: "none" is not always respected

[Natr1x]

I tend to find the snippet completions of callables to be more trouble than they are worth, especially when it comes to initiating structs.
And so I want to turn them off.

Unfortunately the rust-analyzer.completion.callable.snippets config does not seem to apply to struct completions.

Since I haven't been able to find any other setting specifically for structs I can only assume that this is a bug.

rust-analyzer version: rust-analyzer 1.84.1 (e71f9a9 2025-01-27)

rustc version: rustc 1.84.1 (e71f9a9a9 2025-01-27)

editor or extension:

NVIM v0.10.4
Build type: RelWithDebInfo
LuaJIT 2.1.1736781742

relevant settings:

default_settings = {
  -- rust-analyzer language server configuration
  ['rust-analyzer'] = {
    completion = {
      postfix = {
        enable = false,
      },
      autoimport = {
        enable = false,
      },
      callable = {
        snippets = "none",
      },
    },
  },
}

code snippet to reproduce:

mod amod {
    #[derive(Debug)]
    pub struct AnInitializerStructuWithManyFields {
        pub a_long_field_name: u32,
        pub b_long_field_name: u32,
        pub c_long_field_name: u32,
        pub d_long_field_name: u32,
        pub e_long_field_name: u32,
        pub f_long_field_name: u32,
        pub g_long_field_name: u32,
        pub h_long_field_name: u32,
        pub i_long_field_name: u32,
        pub j_long_field_name: u32,
        pub k_long_field_name: u32,
    }

    pub fn a_function_initialized_with_said_struct(init_args: &AnInitializerStructuWithManyFields) {
        println!("{init_args:?}");
    }
}

fn main() {
    // Start typing the following and let analyzer suggest completions:
    // amod::a_function_initialized_with_said_struct(&am

    // Expected completion behavior:
    amod::a_function_initialized_with_said_struct(&amod::AnInitializerStructuWithManyFields

    // Actual (incredibly unhelpful) behaviour:
    amod::a_function_initialized_with_said_struct(&amod::AnInitializerStructuWithManyFields { a_long_field_name: (), b_long_field_name: (), c_long_field_name: (), d_long_field_name: (), e_long_field_name: (), f_long_field_name: (), g_long_field_name: (), h_long_field_name: (), i_long_field_name: (), j_long_field_name: (), k_long_field_name: () }

    // If you continue to type until you complete the namespace before letting analyzer suggest completions:
    // Eg. `amod::a_function_initialized_with_said_struct(&amod::`
    // Then I am offered the expected completion of simply the plain struct name.
    // Which 9/10 is what you want if the structure has more than 3 fields since
    // then you can make use of init shorthands and defaults like below:

    let f_long_field_name = 42;
    amod::a_function_initialized_with_said_struct(&amod::AnInitializerStructuWithManyFields {
        f_long_field_name,
        ..Default::default()
    });
}

I don't think we have a setting for that, although we do show the bare path completion, even though it may come later. I guess we could add such setting.
