What an app decides about each control facet_html_with draws.

index is the value’s position in Facet::values. Every method defaults to what facet_html writes: a button, aria-pressed, nothing more.

Provided Methods

fn draws(&mut self, _index: usize, _control: FacetControl) -> bool

Whether the control is drawn at all.

fn open( &mut self, _index: usize, _control: FacetControl, out: &mut String, ) -> &'static str

Open the control’s tag up to its class, and return the tag that closes it.

fn state( &mut self, _index: usize, _control: FacetControl, on: bool, out: &mut String, )

Say whether the control is in force, as an attribute.

fn attrs(&mut self, _index: usize, _control: FacetControl, _out: &mut String)

Attributes written after the emitter’s own, before the tag closes.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
