Trait IProperty 

pub trait IProperty: INode {
    // Required methods
    fn get_value(&self) -> &dyn IValue;
    fn set_value(&mut self, val: &dyn IValue, writer: &mut dyn IWrite) -> bool;
    fn set(&mut self, val: &str, writer: &mut dyn IWrite) -> bool;
    fn reset(&mut self);
    fn default_value(&self) -> &dyn IValue;
    fn state(&self) -> PropState;

    // Provided methods
    fn flags(&self) -> u32 { ... }
    fn values(&self) -> Option<&[&str]> { ... }
}

Property node interface.

Provides an object safe interface for properties, type erasing its implementation.

Required Methods

fn get_value(&self) -> &dyn IValue

Gets the value.

fn set_value(&mut self, val: &dyn IValue, writer: &mut dyn IWrite) -> bool

Sets the value.

fn set(&mut self, val: &str, writer: &mut dyn IWrite) -> bool

Sets the value parsed from string.

fn reset(&mut self)

Resets the value to its default.

If this operation fails (for eg. read-only properties), it does so silently.

fn default_value(&self) -> &dyn IValue

Gets the default value.

fn state(&self) -> PropState

Returns the state of the property.

Provided Methods

fn flags(&self) -> u32

Returns the flags associated with the property.

The meaning of this value is defined by the caller.

fn values(&self) -> Option<&[&str]>

Returns a list of valid value strings for this property.

None if the question is not relevant, eg. string or number nodes.

Trait Implementations

impl Debug for dyn IProperty + '_

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

Formats the value using the given formatter.
