If a `string`, it is prepended to each diagnostic
                            in the window with no highlight. Overrides the
                            setting from |vim.diagnostic.config()|.
      • {suffix}?         (`string|table|(fun(diagnostic:vim.Diagnostic,i:integer,total:integer): string, string)`)
                          Same as {prefix}, but appends the text to the
                          diagnostic instead of prepending it. Overrides the
                          setting from |vim.diagnostic.config()|.
      • {focus_id}?       (`string`)
      • {border}?         (`string`) see |nvim_open_win()|.

*vim.diagnostic.Opts.Jump*

    Fields: ~
      • {on_jump}?   (`fun(diagnostic:vim.Diagnostic?, bufnr:integer)`)
                     Default value of the {on_jump} parameter of
                     |vim.diagnostic.jump()|.
      • {wrap}?      (`boolean`, default: true) Default value of the {wrap}
                     parameter of |vim.diagnostic.jump()|.
      • {severity}?  (`vim.diagnostic.SeverityFilter`) Default value of the
                     {severity} parameter of |vim.diagnostic.jump()|.

*vim.diagnostic.Opts.Signs*

    Fields: ~
      • {severity}?  (`vim.diagnostic.SeverityFilter`) Only show signs for
                     diagnostics matching the given severity
                     |diagnostic-severity|
      • {priority}?  (`integer`, default: `10`) Base priority to use for
                     signs. When {severity_sort} is used, the priority of a
                     sign is adjusted based on its severity. Otherwise, all
                     signs use the same priority.
      • {text}?      (`table<vim.diagnostic.Severity,string>`) A table mapping
                     |diagnostic-severity| to the sign text to display in the
                     sign column. The default is to use `"E"`, `"W"`, `"I"`,
                     and `"H"` for errors, warnings, information, and hints,
                     respectively. Example: >lua
                         vim.diagnostic.config({
                           signs = { text = { [vim.diagnostic.severity.ERROR] = 'E', ... } }
                         })
<
      • {numhl}?     (`table<vim.diagnostic.Severity,string>`) A table mapping
                     |diagnostic-severity| to the highlight group used for the
                     line number where the sign is placed.
      • {linehl}?    (`table<vim.diagnostic.Severity,string>`) A table mapping
                     |diagnostic-severity| to the highlight group used for the
                     whole line the sign is placed in.

*vim.diagnostic.Opts.Underline*

    Fields: ~
      • {severity}?  (`vim.diagnostic.SeverityFilter`) Only underline
                     diagnostics matching the given severity
                     |diagnostic-severity|.

*vim.diagnostic.Opts.VirtualLines*

    Fields: ~
      • {severity}?      (`vim.diagnostic.SeverityFilter`) Only show virtual
                         lines for diagnostics matching the given severity
                         |diagnostic-severity|
      • {current_line}?  (`boolean`, default: `false`) Only show diagnostics
                         for the current line.
      • {format}?        (`fun(diagnostic:vim.Diagnostic): string?`) A
                         function that takes a diagnostic as input and returns
                         a string or nil. If the return value is nil, the
                         diagnostic is not displayed by the handler. Else the
                         output text is used to display the diagnostic.

*vim.diagnostic.Opts.VirtualText*

    Fields: ~
      • {severity}?           (`vim.diagnostic.SeverityFilter`) Only show
                              virtual text for diagnostics matching the given
                              severity |diagnostic-severity|
      • {current_line}?       (`boolean`) Show or hide diagnostics based on
                              the current cursor line. If `true`, only
