Module config 

Configuration file discovery and loading.

Provides the three-stage config search (explicit path → ./config.toml → $XDG_CONFIG_HOME/<app>/config.toml) and a generic TOML loader that produces semantic errors.

Structs

CommonConfigFile

Common config-file fields shared by every project crate. Flatten into your ConfigFileRaw with #[serde(flatten)].

Enums

ConfigFileError

Functions

find_config_file

Locate a configuration file using a two-stage search:

load_toml

Deserialise a TOML file into T, wrapping I/O and parse failures in ConfigFileError.

resolve_log_settings

Resolve log_level and log_format from CLI → config-file → defaults.

xdg_config_dir

Resolve $XDG_CONFIG_HOME/<app_name>, falling back to $HOME/.config/<app_name> when the variable is unset.
