}

Config is the root type used for TOML configuration.

See docs at /docs/CONFIG.md generated via config.GenerateDocs from /internal/config/docs.toml

When adding a new field:

  • consider including a unit suffix with the field name
  • TOML is limited to int64/float64, so fields requiring greater range/precision must use non-standard types implementing encoding.TextMarshaler/TextUnmarshaler, like utils.Big and decimal.Decimal
  • std lib types that don't implement encoding.TextMarshaler/TextUnmarshaler (time.Duration, url.URL, big.Int) won't work as expected, and require wrapper types. See models.Duration, models.URL, utils.Big.
