----@field timeout_ms nil|integer Time in milliseconds to block for formatting. Defaults to 1000. No effect if async = true.
----@field bufnr nil|integer Format this buffer (default 0)
----@field async nil|boolean If true the method won't block. Defaults to false. If the buffer is modified before the formatter completes, the formatting will be discarded.
----@field dry_run nil|boolean If true don't apply formatting changes to the buffer
----@field undojoin nil|boolean Use undojoin to merge formatting changes with previous edit (default false)
----@field formatters nil|string[] List of formatters to run. Defaults to all formatters for the buffer filetype.
----@field lsp_format? conform.LspFormatOpts Configure if and when LSP should be used for formatting. Defaults to "never".
----@field quiet nil|boolean Don't show any notifications for warnings or failures. Defaults to false.
----@field range nil|table Range to format. Table must contain `start` and `end` keys with {row, col} tuples using (1,0) indexing. Defaults to current selection in visual mode
