Functions

func Address

func Address() common.Address

Address returns the multi-chain vanity address used by all delegation registries.

Types

type Delegation

type Delegation struct {
	Vault    common.Address
	Delegate common.Address
	Contract eth.NullableAddress
	TokenID  eth.NullableUint256
}

A Delegation is a generalised structure capturing all delegation types. When converted to a Delegation, all type-specific delegations include at least the Vault and Delegate fields. A contract delegation also includes the Contract field, and a token delegation also includes the TokenID on top of this.

func AppendDelegations

func AppendDelegations[T DelegationBuilder](ctx context.Context, curr []*Delegation, fetch func(*bind.CallOpts, common.Address) ([]T, error), vault common.Address) ([]*Delegation, error)

AppendDelegations calls fetch(…, vault), converts all results to *Delegation, and appends them to curr, returning the extended slice. The original slice is unchanged.

The fetch argument is compatible with the following IDelegationRegistry methods without the need to specify T:

GetAppendableDelegatesForAll()
GetContractLevelDelegations()
GetTokenLevelDelegations()

type DelegationBuilder

type DelegationBuilder interface {
	Delegation(vault common.Address) *Delegation
}

A DelegationBuilder can build a Delegation for a given vault address. It is typically a converter from another type.
