How to specify "coverage_file" as an option in Rust language?

[norikatsu]

Hi there,
llvm-cov can now be used as a coverage check method for rust.
You can output an lcov format file with the command below.

$ cargo llvm-cov --lcov --output-path [LCOV_FILE_PATH]

However, nvim-coverage's Rust options do not allow you to set "coverage_file" directly.
Is it possible to set "coverage_file" like in C/C++ and Go?

You can use the load_lcov function for other filetypes, that use the lcov format. This is an example for dart. I am using this function assigned to a keymap.

function()
    -- only for dart files
    if vim.bo.filetype == 'dart' then
        local project_root = require('util').findGitDirectory(vim.loop.cwd())
        if not project_root then
            print('No git directory found')
            return
        end
        local coverage_report = project_root .. '/coverage/lcov.info'
        require('coverage').load_lcov(coverage_report, true)
    else
        print('defaulting to preset file loaction')
        require('coverage').load(true)
    end
end,
