Struct log::MetadataBuilder
source · 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();
