Module nesdie::env

Higher level environment functions which act as a safe wrapper around sys.

Structs

The balance that was attached to the call that will be immediately deposited before the contract execution starts

block_index

Current block index.

block_timestamp

Current block timestamp, i.e, number of non-leap-nanoseconds since January 1, 1970 0:00:00 UTC.

current_account_id

The id of the account that owns the current contract.

epoch_height

Current epoch height.

keccak256

Hashes the random sequence of bytes using keccak256.

keccak512

Hashes the random sequence of bytes using keccak512.

log_str

Log the UTF-8 encodable message.

panic_str

Terminates the execution of the program with the UTF-8 encoded message.

prepaid_gas

The amount of gas attached to the call that can be used to pay for the gas fees.

promise_batch_action_add_key_with_full_access

Add full access key with batch promise.

promise_batch_action_add_key_with_function_call

Add access key with only function call priviledges

promise_batch_action_create_account

Create account with the batch promise.

promise_batch_action_delete_account

Delete account with batch promise.

promise_batch_action_delete_key

Delete access key with batch promise.

promise_batch_action_deploy_contract

Deploy contract with the batch promise.

promise_batch_action_function_call

Call a function within the batch promise.

promise_batch_action_stake

Stake tokens with the promise.

promise_batch_action_transfer

Transfer tokens with the promise.

promise_batch_create

Create a batch promise and return the index of that promise.

promise_batch_then

Schedule a promise after the provided promise index.

promise_create

the given amount and gas.

promise_then

Attaches the callback that is executed after promise pointed by promise_idx is complete.

read_register

Reads the content of the register_id. If register is not used or the buffer is not large enough, an error will be returned.

register_len

Returns the size of the register. If register is not used returns None.

sha256

Hashes the random sequence of bytes using sha256.

state_exists

Returns true if the contract state exists and false otherwise.

state_read_raw

Load the state of the given object. Read raw bytes under the static state key.

state_write_raw

Write bytes under the static state key.

storage_byte_cost

Returns the storage cost per byte.

storage_get_evicted

Reads the most recent value that was evicted with storage_write or storage_remove command.

storage_has_key

Checks if there is a key-value in the storage.

storage_read

Reads the value stored under the given key.

storage_remove

Removes the value stored under the given key. If key-value existed returns true, otherwise false.

storage_usage

Current total storage usage of this smart contract that this account would be paying for.

storage_write

Writes key-value into storage. If another key-value existed in the storage with the same key it returns true, otherwise false.

used_gas

The gas that was already burnt during the contract execution (cannot exceed prepaid_gas)

validator_stake

For a given account return its current stake. If the account is not a validator, returns 0.

validator_total_stake

Returns the total stake of validators in the current epoch.

value_return

Sets the blob of data as the return value of the contract.
