Struct TxidPrefix 

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

First-8-bytes prefix of a txid, packed as a u64. Both From<&Txid> (via from_le_bytes) and From<ByteView> (via from_be_bytes, inverse of the to_be_bytes writer) are host-independent so on-disk keys are portable across architectures.

Methods from Deref<Target = u64>

pub const MIN: u64 = 0

pub const MAX: u64

pub const BITS: u32

Trait Implementations

impl Eq for TxidPrefix

impl From<&Txid> for TxidPrefix

fn from(value: &Txid) -> Self

Converts to this type from the input type.

impl From<&TxidPrefix> for ByteView

fn from(value: &TxidPrefix) -> Self

Converts to this type from the input type.

impl From<ByteView> for TxidPrefix

fn from(value: ByteView) -> Self

Converts to this type from the input type.

impl From<Txid> for TxidPrefix

fn from(value: Txid) -> Self

Converts to this type from the input type.

impl From<TxidPrefix> for ByteView

fn from(value: TxidPrefix) -> Self

Converts to this type from the input type.

impl Hash for TxidPrefix

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 TxidPrefix

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

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

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