Contains the application settings.

The application settings are set with a TOML config file. Settings specified in the config file can be overwritten by environment variables. To do so, set an environment variable with the prefix OPENTALK_CTRL_ followed by the field names you want to set. Nested fields are separated by two underscores __.

OPENTALK_CTRL_<field>__<field-of-field>...

Example

set the database.url field:

OPENTALK_CTRL_DATABASE__URL=postgres://postgres:password123@localhost:5432/opentalk

So the field 'database.max_connections' would resolve to:

OPENTALK_CTRL_DATABASE__MAX_CONNECTIONS=5

Note

Fields set via environment variables do not affect the underlying config file.

Implementation Details:

Setting categories, in which all properties implement a default value, should also implement the Default trait.
