Logger-info
Emit an info-level record through the synchronous logger. This is the convenience wrapper for log(Level::Info, ...).
Interface
pub fn[S : Sink] Logger::info(self : Logger[S], message : String, fields~ : Array[Field] = []) -> Unit {}
input
self : Logger[S]- Logger that should emit the info record.message : String- Informational message text.fields : Array[Field]- Optional structured fields attached to the record.
output
Unit- No return value. The record is handled according to the logger threshold and sink pipeline.
Explanation
Detailed rules explaining key parameters and behaviors
- This helper delegates to
log(Level::Info, ...). Infois the default minimum logger threshold unless changed explicitly.- Per-call target override is not exposed here; use
log(...)if needed. - Context fields, filters, patches, and queue wrappers behave exactly as they do for other write methods.
How to Use
Here are some specific examples provided.
When Emit Normal Application Events
When a service should report standard lifecycle milestones:
logger.info("service started")
In this example, the log event uses the normal informational severity.
When Attach Structured Informational Context
When an info event should include machine-readable metadata:
logger.info("request completed", fields=[field("status", "200")])
In this example, the event remains concise while still carrying useful fields.
Error Case
e.g.:
-
If the logger minimum level is above
Info, the call returns without writing a record. -
If the event needs an explicit alternate target, use
log(...)instead of this shortcut.
Notes
-
This is the most common convenience method for normal application events.
-
Because
Infois often the default threshold, this helper is a common baseline for examples and docs.
