Struct ObjectBuilder

pub struct ObjectBuilder<'a, O> { /* private fields */ }

Implementations

impl<'a, O> ObjectBuilder<'a, O>

where O: IsA<Object> + IsClass,

pub fn type_(&self) -> Type

Gets the type of this builder.

pub fn property( self, name: &'a str, value: impl Into<Value>, ) -> ObjectBuilder<'a, O>

Sets property name to the given value value.

Overrides any default or previously defined value for name.

pub fn property_if( self, name: &'a str, value: impl Into<Value>, predicate: bool, ) -> ObjectBuilder<'a, O>

Sets property name to the given inner value if the predicate evaluates to true.

This has no effect if the predicate evaluates to false, i.e. default or previous value for name is kept.

pub fn property_if_some( self, name: &'a str, value: Option<impl Into<Value>>, ) -> ObjectBuilder<'a, O>

Sets property name to the given inner value if value is Some.

This has no effect if the value is None, i.e. default or previous value for name is kept.

pub fn property_from_iter<V>( self, name: &'a str, iter: impl IntoIterator<Item = impl Into<Value>>, ) -> ObjectBuilder<'a, O>

where V: ValueType + Into<Value> + FromIterator<Value>,

Sets property name using the given ValueType V built from iter’s the Items.

Overrides any default or previously defined value for name.

pub fn property_if_not_empty<V>( self, name: &'a str, iter: impl IntoIterator<Item = impl Into<Value>>, ) -> ObjectBuilder<'a, O>

where V: ValueType + Into<Value> + FromIterator<Value>,

Sets property name using the given ValueType V built from iter’s Items, if iter` is not empty.

This has no effect if iter is empty, i.e. previous property value for name is unchanged.

pub fn build(self) -> O

Build the object with the provided properties.

Panics

This panics if the object is not instantiable, doesn’t have all the given properties or property values of the wrong type are provided.
