Struct NavSection 

pub struct NavSection {
    pub id: String,
    pub title: String,
    pub collapsible: bool,
    pub collapsed: bool,
    pub trailing_action: Option<NavAction>,
    pub empty_caption: Option<String>,
    pub filterable: bool,
    pub items: Vec<NavItem>,
}

A group of destinations under a sentence-case title.

Fields

id: String

title: String

Sentence case (“Mailboxes”, “On this device”). An empty title draws no header: the items stand at the top level.

collapsible: bool

The person can fold the section away.

collapsed: bool

The section starts folded.

trailing_action: Option<NavAction>

A trailing action on the header (usually “New …” with Icon::Plus); reported through NavList::on_section_action.

empty_caption: Option<String>

The one quiet line the section shows while it has no items.

filterable: bool

The window’s filter narrows this section’s items.

items: Vec<NavItem>

Implementations

impl NavSection

pub fn new( id: impl Into<String>, title: impl Into<String>, items: Vec<NavItem>, ) -> NavSection

pub fn untitled(id: impl Into<String>, items: Vec<NavItem>) -> NavSection

Items with no header above them.

pub fn collapsible(self) -> NavSection

pub fn collapsed(self) -> NavSection

Fold the section when it first appears (it stays foldable).

pub fn trailing_action(self, action: NavAction) -> NavSection

pub fn empty_caption(self, caption: impl Into<String>) -> NavSection

What the section says while it holds nothing (“No drafts”): one sentence, in tertiary ink, where its first row would be.

pub fn filterable(self) -> NavSection

Let the window’s filter field (super::NavShell::with_filter) narrow this section’s items. Sections that do not opt in (a list of connections above the tables being filtered) stay as they are.

Trait Implementations

impl Clone for NavSection

fn clone(&self) -> NavSection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NavSection

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

Formats the value using the given formatter.

impl PartialEq for NavSection

fn eq(&self, other: &NavSection) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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