pub struct MetadataBuilder<'a> { /* private fields */ }
Expand description

Builder for Metadata.

Typically should only be used by log library creators or for testing and “shim loggers”. The MetadataBuilder can set the different parameters of a Metadata object, and returns the created object when build is called.

Example

let target = "myApp";
use log::{Level, MetadataBuilder};
let metadata = MetadataBuilder::new()
                    .level(Level::Debug)
                    .target(target)
                    .build();

Implementations

Construct a new MetadataBuilder.

The default options are:

  • level: Level::Info
  • target: ""

Setter for level.

Setter for target.

Returns a Metadata object.
