Struct LeafRequest 

pub struct LeafRequest<'a> {
    pub index: u32,
    pub id: &'a str,
    pub component: &'a str,
    pub part: Option<&'a str>,
    pub owner_component: Option<&'a str>,
    pub props: &'a Map<String, Value>,
    pub text_style: &'a TextStyle,
    pub control: ControlBox,
    pub lines: Option<u32>,
}

One leaf the host must measure. index names the layout node; the host keys its own caches on it. lines = the Text prop (truncate to N lines).

Fields

index: u32

id: &'a str

component: &'a str

The native kind (Text, Button, Input, Extension…).

part: Option<&'a str>

The synthetic part of a native when the leaf is one (Tabs/tab).

owner_component: Option<&'a str>

The component that owns the part (Tabs for Tabs/tab; None for a plain node): a part’s chrome (an icon, a check) depends on it.

props: &'a Map<String, Value>

text_style: &'a TextStyle

control: ControlBox

lines: Option<u32>

Implementations

impl LeafRequest<'_>

pub fn text(&self) -> &str

The text a textual leaf shows.

pub fn display_text(&self) -> Cow<'_, str>

Self::text for a painter: the same prop, and a number or boolean in it shows as its crate::format::display_string (412, 1.5, true), the rule the build applies to bound text props. An FFI host gets this as FfiLeaf.text.

Trait Implementations

impl<'a> Clone for LeafRequest<'a>

fn clone(&self) -> Self

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

Performs copy-assignment from source.

impl<'a> Debug for LeafRequest<'a>

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

Formats the value using the given formatter.
