Trait Update

pub trait Update<Strategy>: AssetDefinition
where
    Strategy: UpdateStrategy,
{
    // Required method
    fn update(
        id: &Self::Id,
        strategy: Strategy,
        update_value: <Strategy as UpdateStrategy>::UpdateValue<'_>,
    ) -> Result<<Strategy as UpdateStrategy>::Success, DispatchError>;
}

A trait representing the ability of a certain asset to update its state information.

This trait can be implemented multiple times using different update strategies.

An update strategy defines how the asset state is identified and what UpdateValue type is used.

Required Methods

fn update( id: &Self::Id, strategy: Strategy, update_value: <Strategy as UpdateStrategy>::UpdateValue<'_>, ) -> Result<<Strategy as UpdateStrategy>::Success, DispatchError>

Update the state information of the asset using the given id, the update strategy, and the strategy’s update_value.

The ID type is retrieved from the AssetDefinition.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
