Struct TransactionLocation

pub struct TransactionLocation {
    pub height: Height,
    pub index: TransactionIndex,
}

A transaction’s location in the chain, by block height and transaction index.

This provides a chain-order list of transactions.

Fields

height: Height

The block height of the transaction.

index: TransactionIndex

The index of the transaction in its block.

Implementations

impl TransactionLocation

pub const MIN: Self = _

The minimum value of a transaction location.

This value corresponds to the genesis coinbase transaction.

pub const MAX: Self = _

The maximum value of a transaction location.

This value corresponds to the last transaction in the highest possible block.

pub fn from_parts( height: Height, index: TransactionIndex, ) -> TransactionLocation

Creates a transaction location from a block height and transaction index.

pub fn from_index(height: Height, transaction_index: u16) -> TransactionLocation

Creates a transaction location from a block height and transaction index.

pub fn from_usize( height: Height, transaction_index: usize, ) -> TransactionLocation

Creates a transaction location from a block height and usize transaction index.

pub fn from_u64(height: Height, transaction_index: u64) -> TransactionLocation

Creates a transaction location from a block height and u64 transaction index.

pub const fn min_for_height(height: Height) -> Self

The minimum value of a transaction location for height.

This value is the coinbase transaction.

pub const fn max_for_height(height: Height) -> Self

The maximum value of a transaction location for height.

This value can be a valid entry, but it won’t fit in a 2MB block.

Trait Implementations

impl Arbitrary for TransactionLocation

type Parameters = (<Height as Arbitrary>::Parameters, <TransactionIndex as Arbitrary>::Parameters)

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = Map<(<Height as Arbitrary>::Strategy, <TransactionIndex as Arbitrary>::Strategy), fn(_: (Height, TransactionIndex)) -> TransactionLocation>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(_top: Self::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for TransactionLocation

fn clone(&self) -> TransactionLocation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TransactionLocation

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

Formats the value using the given formatter.

impl Default for TransactionLocation

fn default() -> TransactionLocation

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TransactionLocation

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromDisk for TransactionLocation

fn from_bytes(disk_bytes: impl AsRef<[u8]>) -> Self

Converts raw disk bytes back into the deserialized type.

impl Hash for TransactionLocation

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 IntoDisk for TransactionLocation

type Bytes = [u8; 5]

The type used to write bytes to disk, and compare a value as a key to on-disk keys.

fn as_bytes(&self) -> Self::Bytes

Converts the current type into serialized raw bytes.

impl Ord for TransactionLocation

fn cmp(&self, other: &TransactionLocation) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for TransactionLocation

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for TransactionLocation

fn partial_cmp(&self, other: &TransactionLocation) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for TransactionLocation

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
