Struct tracing_forest::tag::Builder

pub struct Builder<S, I> { /* private fields */ }

Incrementally construct Tags.

See Tag::builder for more details.

Implementations

impl<S, I> Builder<S, I>

pub fn prefix(self, prefix: &'static str) -> Builder<S, I>

Set the prefix.

pub fn suffix(self, suffix: &'static str) -> Builder<Suffix, I>

Set the suffix.

pub fn icon(self, icon: char) -> Builder<S, Icon>

Set the icon.

pub fn level(self, level: Level) -> Builder<Suffix, Icon>

Set the suffix and icon using defaults for each [Level].

If the Tag won’t have a prefix, then Tag::from(level) can be used as a shorter alternative.

impl Builder<Suffix, Icon>

pub fn build(self) -> Tag

Complete the Tag.

This can only be called once a suffix and an icon have been provided via .suffix(...) and .icon(...), or alternatively just .level(...).

Trait Implementations

impl<S: Clone, I: Clone> Clone for Builder<S, I>

fn clone(&self) -> Builder<S, I>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<S: PartialEq, I: PartialEq> PartialEq<Builder<S, I>> for Builder<S, I>

fn eq(&self, other: &Builder<S, I>) -> 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.
