Struct rerun::external::log::MetadataBuilder

pub struct MetadataBuilder<'a> {
    pub(crate) metadata: Metadata<'a>,
}

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();

Fields

metadata: Metadata<'a>

Implementations

impl<'a> MetadataBuilder<'a>

pub fn new() -> MetadataBuilder<'a>

Construct a new MetadataBuilder.

The default options are:

• level: Level::Info
• target: ""

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

Setter for level.

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

Setter for target.

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

Returns a Metadata object.

Trait Implementations

impl<'a> Debug for MetadataBuilder<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'a> Default for MetadataBuilder<'a>

fn default() -> MetadataBuilder<'a>

Returns the “default value” for a type.

impl<'a> Hash for MetadataBuilder<'a>

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> Ord for MetadataBuilder<'a>

fn cmp(&self, other: &MetadataBuilder<'a>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<'a> PartialEq for MetadataBuilder<'a>

fn eq(&self, other: &MetadataBuilder<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> PartialOrd for MetadataBuilder<'a>

fn partial_cmp(&self, other: &MetadataBuilder<'a>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
