pub fn get_config_from_file<P>(path: P) -> Result<ConfFile, LeptosConfigError>
where
    P: AsRef<Path>,

Loads LeptosOptions from a Cargo.toml with layered overrides. Leptos will read in the settings itself.

This option currently does not allow dashes in file or folder names, as all dashes become underscores.

Errors

• path was not found, or other I/O error has occurred;
• get_config_from_str returned an error.
