Struct ClrPropertyInfo 

pub struct ClrPropertyInfo { /* private fields */ }

A property description built from accessor closures. This is what compiled bindings use to read and write plain properties.

Implementations

impl ClrPropertyInfo

pub fn new( name: &str, getter: Option<PropertyGetter>, setter: Option<PropertySetter>, property_type: ValueType, ) -> Self

Creates a property description from untyped accessors.

pub fn new_fallible( name: &str, getter: Option<FalliblePropertyGetter>, setter: Option<PropertySetter>, property_type: ValueType, ) -> Self

Creates a property description from untyped accessors, with a getter that can fail.

pub fn with_boxed_accessors( self, getter: Option<BoxedPropertyGetter>, setter: Option<BoxedPropertySetter>, ) -> Self

Adds accessors that take the owner as an untyped handle. A property description built over accessors that need the handle of the owner and not only a view of it (the invokers of markup metadata) is read and written through them by the boxed forms of the contract (IPropertyInfo::get_boxed, IPropertyInfo::try_get_boxed, IPropertyInfo::set_boxed).

pub fn read_only_fallible<O: 'static, K: PropertyKind>( name: &str, get: impl Fn(&O) -> Result<K::Typed, BindingError> + 'static, ) -> Self

A read-only property of owner type O whose getter can fail, the way the getter of an indexer throws for a bad index or key.

pub fn read_write_fallible<O: 'static, K: PropertyKind>( name: &str, get: impl Fn(&O) -> Result<K::Typed, BindingError> + 'static, set: impl Fn(&O, K::Typed) -> Result<(), BindingError> + 'static, ) -> Self

A read-write property of owner type O whose getter and setter can fail.

pub fn read_only<O: 'static, K: PropertyKind>( name: &str, get: impl Fn(&O) -> K::Typed + 'static, ) -> Self

A read-only property of owner type O, from a typed getter.

pub fn read_write<O: 'static, K: PropertyKind>( name: &str, get: impl Fn(&O) -> K::Typed + 'static, set: impl Fn(&O, K::Typed) + 'static, ) -> Self

A read-write property of owner type O, from typed accessors.

pub fn read_write_validated<O: 'static, K: PropertyKind>( name: &str, get: impl Fn(&O) -> K::Typed + 'static, set: impl Fn(&O, K::Typed) -> Result<(), BindingError> + 'static, ) -> Self

A read-write property whose setter can reject values.

Trait Implementations

impl IPropertyInfo for ClrPropertyInfo

fn as_any(&self) -> Option<&dyn Any>

The implementing value, for casting to its concrete type (as_any()?.downcast_ref::<T>()): the equivalent of is/as on the contract. None for an implementation that does not expose itself.

fn name(&self) -> &str

The name of the property.

fn get(&self, target: &dyn AnyValue) -> Option<BoxedValue>

Reads the property from target. Null is None.

fn try_get( &self, target: &dyn AnyValue, ) -> Result<Option<BoxedValue>, BindingError>

Reads the property from target. An Err is the equivalent of the getter throwing, for example because target is not of the type that declares the property.

fn set( &self, target: &dyn AnyValue, value: Option<&BoxedValue>, ) -> Result<(), BindingError>

Writes the property on target. An Err is the equivalent of the setter throwing.

fn get_boxed(&self, target: &BoxedValue) -> Option<BoxedValue>

get for an owner known as an untyped handle. The accessors of binding paths read through the boxed forms, so that a property description whose accessors need the handle of the owner (not only a view of it) can override them; the defaults forward to the forms taking a view. Override the three boxed forms together.

fn try_get_boxed( &self, target: &BoxedValue, ) -> Result<Option<BoxedValue>, BindingError>

try_get for an owner known as an untyped handle.

fn set_boxed( &self, target: &BoxedValue, value: Option<&BoxedValue>, ) -> Result<(), BindingError>

set for an owner known as an untyped handle.

fn can_set(&self) -> bool

fn can_get(&self) -> bool

fn property_type(&self) -> ValueType

The type of the property’s value.

fn as_ferro_property(&self) -> Option<&'static FerroProperty>

The registered property this description is, if it is one (the cast of a property description back to the registered property class).

impl MarkupTyped for ClrPropertyInfo

const MARKUP: &'static MarkupType

The markup metadata of the type.
