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();
Implementations
sourceimpl<'a> MetadataBuilder<'a>
impl<'a> MetadataBuilder<'a>
sourcepub fn new() -> MetadataBuilder<'a>
pub fn new() -> MetadataBuilder<'a>

.
The default options are:
level
:Level::Info
target
:""
sourcepub fn level(&mut self, arg: Level) -> &mut MetadataBuilder<'a>
pub fn level(&mut self, arg: Level) -> &mut MetadataBuilder<'a>
Setter for level
.
sourcepub fn target(&mut self, target: &'a str) -> &mut MetadataBuilder<'a>
pub fn target(&mut self, target: &'a str) -> &mut MetadataBuilder<'a>
Setter for target
.
