Trait cvar::IProperty

pub trait IProperty: INode {
    fn get(&self) -> String;
    fn set(
        &mut self, 
        val: &str
    ) -> Result<(), Box<dyn StdError + Send + Sync + 'static>>;
    fn reset(&mut self);
    fn default(&self) -> String;
    fn state(&self) -> PropState;

    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(&self) -> String

Gets the value as a string.

fn set(
    &mut self,
    val: &str
) -> Result<(), Box<dyn StdError + Send + Sync + 'static>>

Sets the value.

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(&self) -> String

Gets the default value as a string.

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.
