Struct log::MetadataBuilder [] [src]

pub struct MetadataBuilder<'a> { /* fields omitted */ }

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();
