min_heap

Structs

DisplayOption

A wrapper around Option that provides native Display trait. Simplifies propagating automatic Display trait on parent structs.

MaybeValidated

A data structure for tagging data as already being validated to prevent redundant work.

Serializable

Functions

account_is_valid

From unc-account-id version 0.7.2, is_valid returns true for ETH-implicit accounts. This function is a wrapper for is_valid method so that we can easily differentiate its behavior based on whether ETH-implicit accounts are enabled.

create_action_hash

Creates a new action_hash from a given receipt, a block hash and an action index. This method is backward compatible, so it takes the current protocol version.

create_data_id

Creates a new data_id from a given action hash, a block hash and a data index. This method is backward compatible, so it takes the current protocol version.

create_random_seed

Creates a unique random seed to be provided to VMContext from a give action_hash and a given random_seed. This method is backward compatible, so it takes the current protocol version.

create_receipt_id_from_receipt

Creates a new Receipt ID from a given receipt, a block hash and a new receipt index. This method is backward compatible, so it takes the current protocol version.

create_receipt_id_from_transaction

Creates a new Receipt ID from a given signed transaction and a block hash. This method is backward compatible, so it takes the current protocol version.

derive_eth_implicit_account_id

Returns ‘0x’ + keccak256(public_key)[12:32].hex(). This is an ETH-implicit account ID which can be controlled by the corresponding Secp256K1 private key.

derive_unc_account_id

Returns hex-encoded copy of the public key. This is a unc-implicit account ID which can be controlled by the corresponding ED25519 private key.

from_timestamp

Converts timestamp in ns into DateTime UTC time.

generate_random_string

Generate random string of given length

get_block_shard_id

get_block_shard_id_rev

get_num_seats_per_shard

Compute number of seats per shard for given total number of seats and number of shards.

get_outcome_id_block_hash

get_outcome_id_block_hash_rev

index_to_bytes

ser

Wrap an object that implements Serialize into another object that implements Display. When used display in this object it shows its json representation. It is used to display complex objects using tracing.

to_timestamp

Converts DateTime UTC time into timestamp in ns.
