Struct Struct 

pub struct Struct(/* private fields */);

This type represents a runtime instance of structure in .slint.

This can either be an instance of a name structure introduced with the struct keyword in the .slint file, or an anonymous struct written with the { key: value, } notation.

It can be constructed with the FromIterator trait, and converted into or from a Value with the From, TryFrom trait

use core::convert::TryInto;
// Construct a value from a key/value iterator
let value : Value = [("foo".into(), 45u32.into()), ("bar".into(), true.into())]
    .iter().cloned().collect::<Struct>().into();

// get the properties of a `{ foo: 45, bar: true }`
let s : Struct = value.try_into().unwrap();
assert_eq!(s.get_field("foo").cloned().unwrap().try_into(), Ok(45u32));

Implementations

impl Struct

pub fn get_field(&self, name: &str) -> Option<&Value>

Get the value for a given struct field

pub fn set_field(&mut self, name: String, value: Value)

Set the value of a given struct field

pub fn iter(&self) -> impl Iterator<Item = (&str, &Value)>

Iterate over all the fields in this struct

Trait Implementations

impl Clone for Struct

fn clone(&self) -> Struct

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Struct

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

Formats the value using the given formatter.

impl Default for Struct

fn default() -> Struct

Returns the “default value” for a type.

impl From<Struct> for Value

fn from(v: Struct) -> Self

Converts to this type from the input type.

impl FromIterator<(String, Value)> for Struct

fn from_iter<T: IntoIterator<Item = (String, Value)>>(iter: T) -> Self

Creates a value from an iterator.

impl PartialEq for Struct

fn eq(&self, other: &Struct) -> 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.

impl TryFrom<Value> for Struct

type Error = Value

The type returned in the event of a conversion error.

fn try_from(v: Value) -> Result<Struct, Self::Error>

Performs the conversion.
