pub fn load_toml_file_raw(
path: &Path,
) -> Result<Option<NestedTomlTable>, ConfigError>Expand description
Read a TOML file and return the parsed table wrapped in [NestedTomlTable]
(without flattening).
Used internally by #[derive(Config)]-generated code to extract sub-tables
for #[param(nested)] fields. The result is opaque so toml’s types do
not leak into the public API.
Returns Ok(None) if the file does not exist (not an error).
