Struct StandardDecorator 

pub struct StandardDecorator { /* private fields */ }

Default decorator implementation.

Style

Root
├  Item A
│  Description
┊- Small Description
└  Item B
   ├  Item B.a
   ├  Item B.b
   │  └  Item B.b.a
   └  Item B.c

Uses a block length of 3 by default, but can be modified.

Block Level 0

At root item, nothing is rendered.

Block Level 1 or Greater

Every following section describes a style item available to use at styles section (at tree_item!).

Precedence

Some of them will takes precedence of others, such as Last and Dashed, meaning that, when both are opt-in together, it’ll use one which has the most precedence as guide to choose suitable item.

No Effect Combination

Also, there are combinations which has no effect, such as Last and Dashed, as well, they will have no effect by lack of proper character representation or the combination simply does’t makes sense.

When it occurs, it’ll effectively ignore the least preceding style.

Items

Last

No effect: Style::dashed

Takes precedence over: Style::dashed

Entry Kind	Style::last	Style::dashed
Entry::Simple	└	└
Entry::Double	╘	╘
Entry::None	╵	╵

Dashed

No effect: Style::last

Entry Kind	Style::dashed	Style::last1
Entry::Simple	┊-	└
Entry::Double	┊=	╘
Entry::None	┊	╵

---

1. Style::last takes precedence here, as explained, so it’ll display as Style::dashed was ignored, as expected, since there is no available combination to both of them. ↩
