Constants

const StoreKey = authz.ModuleName

StoreKey is the store key string for authz

Variables

var (
	GrantKey         = []byte{0x01} // prefix for each key
	GrantQueuePrefix = []byte{0x02}
)

Keys for store prefixes Items are stored with the following key: values

- 0x01<grant_Bytes>: Grant - 0x02<grant_expiration_Bytes>: GrantQueueItem

Functions

func GrantQueueKey

func GrantQueueKey(expiration time.Time, granter sdk.AccAddress, grantee sdk.AccAddress) []byte

GrantQueueKey - return grant queue store key Key format is

- 0x02<grant_expiration_Bytes>: GrantQueueItem

func GrantQueueTimePrefix

func GrantQueueTimePrefix(expiration time.Time) []byte

GrantQueueTimePrefix - return grant queue time prefix

Types

type Keeper

type Keeper struct {
	// contains filtered or unexported fields
}

func NewKeeper

func NewKeeper(storeKey storetypes.StoreKey, cdc codec.BinaryCodec, router *middleware.MsgServiceRouter, ak authkeeper.AccountKeeper) Keeper

NewKeeper constructs a message authorization Keeper

func (Keeper) DeleteGrant

func (k Keeper) DeleteGrant(ctx sdk.Context, grantee sdk.AccAddress, granter sdk.AccAddress, msgType string) error

DeleteGrant revokes any authorization for the provided message type granted to the grantee by the granter.

func (Keeper) DequeueAndDeleteExpiredGrants

func (k Keeper) DequeueAndDeleteExpiredGrants(ctx sdk.Context) error

DequeueAndDeleteExpiredGrants deletes expired grants from the state and grant queue.

func (Keeper) DispatchActions

func (k Keeper) DispatchActions(ctx sdk.Context, grantee sdk.AccAddress, msgs []sdk.Msg) ([][]byte, error)

DispatchActions attempts to execute the provided messages via authorization grants from the message signer to the grantee.

func (Keeper) Exec

func (k Keeper) Exec(goCtx context.Context, msg *authz.MsgExec) (*authz.MsgExecResponse, error)

Exec implements the MsgServer.Exec method.

func (Keeper) ExportGenesis

func (k Keeper) ExportGenesis(ctx sdk.Context) *authz.GenesisState

ExportGenesis returns a GenesisState for a given context.

func (Keeper) GetAuthorizations

func (k Keeper) GetAuthorizations(ctx sdk.Context, grantee sdk.AccAddress, granter sdk.AccAddress) ([]authz.Authorization, error)

GetAuthorizations Returns list of `Authorizations` granted to the grantee by the granter.

func (Keeper) Grant

func (k Keeper) Grant(goCtx context.Context, msg *authz.MsgGrant) (*authz.MsgGrantResponse, error)

GrantAuthorization implements the MsgServer.Grant method to create a new grant.

func (Keeper) GranteeGrants

func (k Keeper) GranteeGrants(c context.Context, req *authz.QueryGranteeGrantsRequest) (*authz.QueryGranteeGrantsResponse, error)

GranteeGrants implements the Query/GranteeGrants gRPC method.

func (Keeper) GranterGrants

func (k Keeper) GranterGrants(c context.Context, req *authz.QueryGranterGrantsRequest) (*authz.QueryGranterGrantsResponse, error)

GranterGrants implements the Query/GranterGrants gRPC method.

func (Keeper) Grants

func (k Keeper) Grants(c context.Context, req *authz.QueryGrantsRequest) (*authz.QueryGrantsResponse, error)

Authorizations implements the Query/Grants gRPC method.

func (Keeper) InitGenesis

func (k Keeper) InitGenesis(ctx sdk.Context, data *authz.GenesisState)

InitGenesis new authz genesis

func (Keeper) IterateGrants

func (k Keeper) IterateGrants(ctx sdk.Context,
	handler func(granterAddr sdk.AccAddress, granteeAddr sdk.AccAddress, grant authz.Grant) bool)

IterateGrants iterates over all authorization grants This function should be used with caution because it can involve significant IO operations. It should not be used in query or msg services without charging additional gas.

func (Keeper) Logger

func (k Keeper) Logger(ctx sdk.Context) log.Logger

Logger returns a module-specific logger.

func (Keeper) Revoke

func (k Keeper) Revoke(goCtx context.Context, msg *authz.MsgRevoke) (*authz.MsgRevokeResponse, error)

RevokeAuthorization implements the MsgServer.Revoke method.

func (Keeper) SaveGrant

func (k Keeper) SaveGrant(ctx sdk.Context, grantee, granter sdk.AccAddress, authorization authz.Authorization, expiration time.Time) error

SaveGrant method grants the provided authorization to the grantee on the granter's account with the provided expiration time and insert authorization key into the grants queue. If there is an existing authorization grant for the same `sdk.Msg` type, this grant overwrites that.

type Migrator

type Migrator struct {
	// contains filtered or unexported fields
}

Migrator is a struct for handling in-place store migrations.

func NewMigrator

func NewMigrator(keeper Keeper) Migrator

NewMigrator returns a new Migrator.

func (Migrator) Migrate1to2

func (m Migrator) Migrate1to2(ctx sdk.Context) error

Migrate1to2 migrates from version 1 to 2.
