Callbacks executed on asset lifecycle and balance-change events.

Provided Methods

fn created(_id: &AssetId, _owner: &AccountId) -> Result<(), ()>

Indicates that asset with id was successfully created by the owner

fn destroyed(_id: &AssetId) -> Result<(), ()>

Indicates that asset with id has just been destroyed

fn issued(_id: &AssetId, _owner: &AccountId, _amount: Balance)

Indicates that amount of asset id was minted into owner, increasing total supply.

fn transferred( _id: &AssetId, _from: &AccountId, _to: &AccountId, _amount: Balance, )

Indicates that amount of asset id was moved from from to to.

fn burned(_id: &AssetId, _owner: &AccountId, _amount: Balance)

Indicates that amount of asset id was burned from owner, decreasing total supply.

fn deposited(_id: &AssetId, _who: &AccountId, _amount: Balance)

Indicates that amount of asset id was credited to who without changing total supply.

fn withdrawn(_id: &AssetId, _who: &AccountId, _amount: Balance)

Indicates that amount of asset id was debited from who without changing total supply.

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.
