Struct HeaderTitles 

pub struct HeaderTitles {
    pub title: Option<&'static str>,
    pub subtitle: Option<&'static str>,
}

Title band drawn above a layout. The title slot renders larger / brighter on the left of the band; the subtitle slot renders smaller / dimmer on the right. Each slot is independently optional - set either, both, or neither.

Use HeaderTitles::title / HeaderTitles::subtitle / HeaderTitles::pair for the common cases; build the struct directly only when you want to set a non-default combination (e.g. via .. syntax over an existing instance).

Fields

title: Option<&'static str>

subtitle: Option<&'static str>

Implementations

impl HeaderTitles

pub const fn none() -> HeaderTitles

Both slots empty - no header band is drawn.

pub const fn title(s: &'static str) -> HeaderTitles

Title only; subtitle slot stays empty.

pub const fn subtitle(s: &'static str) -> HeaderTitles

Subtitle only; title slot stays empty.

pub const fn pair(title: &'static str, subtitle: &'static str) -> HeaderTitles

Both slots set.

pub const fn is_empty(&self) -> bool

true when neither slot is set - caller should skip the header band entirely.
