class log_state_t#

Class to represent the log state. The log state is the state which contains the log recorded by the execution of the transaction. YP: accrued transaction substate \(A_{l}\) for log series

Public Types

typedef arith_env_t<params> arith_t#

The arithmetical environment used by the arbitrary length integer library.

typedef arith_t::bn_t bn_t#

The arbitrary length integer type.

typedef cgbn_mem_t<params::BITS> evm_word_t#

The arbitrary length integer type used for the storage. It is defined as the EVM word type.

Public Functions

inline __host__ __device__ __forceinline__ log_state_t (arith_t &arith, log_state_data_t *content)

Constructor with given content.

Parameters

  • arith – [in] The arithmetical environment

  • content – [in] The content of the log state

inline __host__ __device__ __forceinline__ log_state_t (arith_t &arith)

Constructor without content.

Parameters

arith – [in] The arithmetical environment

inline __host__ __device__ __forceinline__ ~log_state_t ()

The destructor. It frees the memory allocated for the log state.

inline __host__ __device__ __forceinline__ void grow ()

inline __host__ __device__ __forceinline__ void update_with_child_state (log_state_t &child)

Update the current touch state with the touch state of a children

Parameters

child – [in] The touch state of the child

inline __host__ __device__ __forceinline__ void to_log_state_data_t (log_state_data_t &log_state_data)

Copy the content of the touch state to the given touch state data.

Parameters

touch_state_data – [out] The touch state data

inline __host__ __device__ __forceinline__ void print ()

Print the state.

inline __host__ __forceinline__ cJSON * json ()

Get json of the state

Returns

The json of the state

Public Members
