Struct hedera::FileId

pub struct FileId {
    pub shard: u64,
    pub realm: u64,
    pub num: u64,
    pub checksum: Option<Checksum>,
}

The unique identifier for a file on Hedera.

Fields

shard: u64

The shard number.

realm: u64

The realm number.

num: u64

The file number.

checksum: Option<Checksum>

A checksum if the file ID was read from a user inputted string which inclueded a checksum

Implementations

impl FileId

pub const ADDRESS_BOOK: Self = _

Address of the public node address book for the current network.

pub const FEE_SCHEDULE: Self = _

Address of the current fee schedule for the network.

pub const EXCHANGE_RATES: Self = _

Address of the current exchange rate of HBAR to USD.

pub const fn new(shard: u64, realm: u64, num: u64) -> Self

Create a FileId with the given shard.realm.num.

pub fn from_bytes(bytes: &[u8]) -> Result<Self>

Create a new FileId from protobuf-encoded bytes.

Errors

• Error::FromProtobuf if decoding the bytes fails to produce a valid protobuf.
• Error::FromProtobuf if decoding the protobuf fails.

pub fn from_solidity_address(address: &str) -> Result<Self>

Create a FileId from a solidity address.

Errors

• Error::BasicParse if address cannot be parsed as a solidity address.

pub fn to_bytes(&self) -> Vec<u8>

Convert self to a protobuf-encoded Vec<u8>.

pub fn to_solidity_address(&self) -> Result<String>

Convert self into a solidity address

Errors

• Error::BasicParse if self.shard is larger than u32::MAX.

pub fn to_string_with_checksum(&self, client: &Client) -> String

Convert self to a string with a valid checksum.

pub fn validate_checksum(&self, client: &Client) -> Result<(), Error>

Validates self.checksum (if it exists) for client.

Errors

• Error::BadEntityId if there is a checksum, and the checksum is not valid for the client’s ledger_id.

Trait Implementations

impl Clone for FileId

fn clone(&self) -> FileId

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FileId

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for FileId

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<EntityId> for FileId

fn from(value: EntityId) -> Self

Converts to this type from the input type.

impl From<u64> for FileId

fn from(num: u64) -> Self

Converts to this type from the input type.

impl FromStr for FileId

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for FileId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FileId

fn eq(&self, other: &FileId) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
