Struct TemplatePartAttribute 

pub struct TemplatePartAttribute {
    pub name: &'static str,
    pub type_: &'static TypeInfo,
    pub is_required: bool,
}

Declares that a templated control expects a named part of a given type in its control template.

Classes expose their parts through a template_parts() function.

Fields

name: &'static str

The pre-defined name of the part.

type_: &'static TypeInfo

The type of the named part: the part is of this class or a class derived from it.

is_required: bool

Whether the part is required to be present in the template. A required part not found in the template is an error.

pub const fn new(name: &'static str, type_: &'static TypeInfo) -> Self

Declares an optional part.

pub const fn required(name: &'static str, type_: &'static TypeInfo) -> Self

Declares a required part.
