Sink-config-new
Construct a SinkConfig value for config-driven logger assembly. This constructor stores sink shape and sink-specific settings as typed data for later runtime building.
Interface
pub fn SinkConfig::new(
kind~ : SinkKind = SinkKind::Console,
path~ : String = "",
append~ : Bool = true,
auto_flush~ : Bool = true,
rotation~ : FileRotation? = None,
text_formatter~ : TextFormatterConfig = default_text_formatter_config(),
) -> SinkConfig {
input
kind : SinkKind- Sink variant such asConsole,JsonConsole,TextConsole, orFile.path : String- File path used whenkind=File.append : Bool- File append policy.auto_flush : Bool- File auto-flush policy.rotation : FileRotation?- Optional file rotation policy.text_formatter : TextFormatterConfig- Formatter config used by text console or file text rendering.
output
SinkConfig- Typed sink configuration used byLoggerConfig.
Explanation
Detailed rules explaining key parameters and behaviors
- The constructor stores the supplied sink-shape and file-specific fields directly.
kinddefaults toSinkKind::Console.text_formatterdefaults todefault_text_formatter_config()so text-oriented sink config always has a formatter config available.- File-only options are stored even though only
kind=Fileactually consumes them at runtime.
How to Use
Here are some specific examples provided.
When Build A Text Console Config
When runtime output should be text-formatted through config data:
let sink = SinkConfig::new(
kind=SinkKind::TextConsole,
text_formatter=TextFormatterConfig::new(show_timestamp=false),
)
In this example, the formatter choice is embedded directly into sink config.
When Build A File Sink Config
When file behavior should be data-driven:
let sink = SinkConfig::new(
kind=SinkKind::File,
path="app.log",
rotation=Some(file_rotation(1024, max_backups=2)),
)
In this example, file location and retention policy are part of the same sink definition.
Error Case
e.g.:
-
If
kind=Filebutpathis empty, the config object is still constructible, but runtime usage should be evaluated carefully. -
If
kindis non-file, file-specific options may simply be unused by the runtime builder.
Notes
-
This constructor builds sink-shape configuration, not the runtime sink itself.
-
Use
sink_config_to_json(...)andstringify_sink_config(...)for export.
