Struct `MetadataBuilder`

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

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

`impl<'a> MetadataBuilder<'a>`

fn new() -> MetadataBuilder<'a>

Construct a new MetadataBuilder.

The default options are:

level: Level::Info
target: ""

fn level(&mut self, arg: Level) -> &mut MetadataBuilder<'a>

Setter for level.

fn target(&mut self, target: &'a str) -> &mut MetadataBuilder<'a>

Setter for target.

fn build(&self) -> Metadata<'a>

Returns a Metadata object.
