Types ¶
type AcceptContext ¶
type AcceptContext struct {
SnowCtx *snow.Context
Warp WarpMessageWriter
}
AcceptContext defines the context passed in to a precompileconfig's Accepter
type Accepter ¶
type Accepter interface {
Accept(acceptCtx *AcceptContext, blockHash common.Hash, blockNumber uint64, txHash common.Hash, logIndex int, topics []common.Hash, logData []byte) error
}
Accepter is an optional interface for StatefulPrecompiledContracts to implement. If implemented, Accept will be called for every log with the address of the precompile when the block is accepted. WARNING: If you are implementing a custom precompile, beware that subnet-evm will not maintain backwards compatibility of this interface and your code should not rely on this. Designed for use only by precompiles that ship with subnet-evm.
type ChainConfig ¶
type ChainConfig interface {
// GetFeeConfig returns the original FeeConfig that was set in the genesis.
GetFeeConfig() commontype.FeeConfig
// AllowedFeeRecipients returns true if fee recipients are allowed in the genesis.
AllowedFeeRecipients() bool
// IsDurango returns true if the time is after Durango.
IsDurango(time uint64) bool
}
ChainContext defines an interface that provides information to a stateful precompile about the chain configuration. The precompile can access this information to initialize its state.
type Config ¶
type Config interface {
// Key returns the unique key for the stateful precompile.
Key() string
// Timestamp returns the timestamp at which this stateful precompile should be enabled.
// 1) 0 indicates that the precompile should be enabled from genesis.
// 2) n indicates that the precompile should be enabled in the first block with timestamp >= [n].
// 3) nil indicates that the precompile is never enabled.
Timestamp() *uint64
// IsDisabled returns true if this network upgrade should disable the precompile.
IsDisabled() bool
// Equal returns true if the provided argument configures the same precompile with the same parameters.
Equal(Config) bool
// Verify is called on startup and an error is treated as fatal. Configure can assume the Config has passed verification.
Verify(ChainConfig) error
}
StatefulPrecompileConfig defines the interface for a stateful precompile to be enabled via a network upgrade.

type Predicater ¶
type Predicater interface {
PredicateGas(predicateBytes []byte) (uint64, error)
VerifyPredicate(predicateContext *PredicateContext, predicateBytes []byte) error
}
Predicater is an optional interface for StatefulPrecompileContracts to implement. If implemented, the predicate will be called for each predicate included in the access list of a transaction. PredicateGas will be called while calculating the IntrinsicGas of a transaction causing it to be dropped if the total gas goes above the tx gas limit. VerifyPredicate is used to populate a bit set of predicates verified prior to block execution, which can be accessed via the StateDB during execution. The bitset is stored in the block, so that historical blocks can be re-verified without calling VerifyPredicate.

Upgrade contains the timestamp for the upgrade along with a boolean [Disable]. If [Disable] is set, the upgrade deactivates the precompile and clears its storage.
func (*Upgrade) Equal ¶
Equal returns true iff [other] has the same blockTimestamp and has the same on value for the Disable flag.
func (*Upgrade) IsDisabled ¶
IsDisabled returns true if the network upgrade deactivates the precompile.
type WarpMessageWriter ¶

AddMessage(unsignedMessage *warp.UnsignedMessage) error
