Json-console-sink

Create the built-in JSON console sink. This sink writes records as structured JSON text and is useful when stdout is consumed by machines rather than humans.

Interface

pub fn json_console_sink() -> JsonConsoleSink {

output

• JsonConsoleSink - Sink that writes records to the console as JSON.

Explanation

Detailed rules explaining key parameters and behaviors

• This sink emits JSON rather than human-focused text formatting.
• It is a direct synchronous sink that can be passed to Logger::new(...).
• Use it when structured logs should be parsed, shipped, or inspected programmatically.

How to Use

Here are some specific examples provided.

When Need Structured Stdout Logs

When log consumers expect machine-readable output:

let logger = Logger::new(json_console_sink(), target="api")
logger.info("ready", fields=[field("service", "bitlogger")])

In this example, the emitted console line is JSON-shaped.

Error Case

e.g.:

• If human-focused text formatting is required, use a text console sink instead.

• Console output still depends on the current runtime environment.

Notes

1. This sink is useful for structured stdout pipelines.

2. It pairs naturally with field-heavy logging.
