Struct TxId

pub struct TxId(/* private fields */);

The identifier for a Zcash transaction.

• For v1-4 transactions, this is a double-SHA-256 hash of the encoded transaction. This means that it is malleable, and only a reliable identifier for transactions that have been mined.
• For v5 transactions onwards, this identifier is derived only from “effecting” data, and is non-malleable in all contexts.

Implementations

impl TxId

pub const fn from_bytes(bytes: [u8; 32]) -> Self

pub fn read<R: Read>(reader: R) -> Result<Self>

pub fn write<W: Write>(&self, writer: W) -> Result<()>

Trait Implementations

impl AsRef<[u8; 32]> for TxId

fn as_ref(&self) -> &[u8; 32]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for TxId

fn clone(&self) -> TxId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TxId

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

Formats the value using the given formatter.

impl Display for TxId

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

Formats the value using the given formatter.

impl DynamicUsage for TxId

fn dynamic_usage(&self) -> usize

Returns a best estimate of the amount of heap-allocated memory used by this type.

fn dynamic_usage_bounds(&self) -> (usize, Option<usize>)

Returns the lower and upper bounds on the amount of heap-allocated memory used by this type.

impl From<TxId> for [u8; 32]

fn from(value: TxId) -> Self

Converts to this type from the input type.

impl Hash for TxId

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 Ord for TxId

fn cmp(&self, other: &TxId) -> 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 TxId

fn eq(&self, other: &TxId) -> 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 TxId

fn partial_cmp(&self, other: &TxId) -> 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.
