Struct AltBlockHeight

#[repr(C)]
pub struct AltBlockHeight {
    pub chain_id: RawChainId,
    pub height: usize,
}

Represents the height of a block on an alt-chain.

use cuprate_database::Storable;
use cuprate_types::ChainId;

// Assert Storable is correct.
let a: AltBlockHeight = AltBlockHeight {
    chain_id: ChainId(1.try_into().unwrap()).into(),
    height: 1,
};
let b = Storable::as_bytes(&a);
let c: AltBlockHeight = Storable::from_bytes(b);
assert_eq!(a, c);

Size & Alignment

assert_eq!(size_of::<AltBlockHeight>(), 16);
assert_eq!(align_of::<AltBlockHeight>(), 8);

Fields

chain_id: RawChainId

The ChainId of the chain this alt block is on, in raw form.

height: usize

The height of this alt-block.

Trait Implementations

impl Clone for AltBlockHeight

fn clone(&self) -> AltBlockHeight

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AltBlockHeight

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

Formats the value using the given formatter.

impl Hash for AltBlockHeight

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 Key for AltBlockHeight

const KEY_COMPARE: KeyCompare = KeyCompare::Default

Compare 2 Key’s against each other.

impl Ord for AltBlockHeight

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

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

fn partial_cmp(&self, other: &AltBlockHeight) -> 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 Zeroable for AltBlockHeight

fn zeroed() -> Self

Calls zeroed.

impl Copy for AltBlockHeight

impl Eq for AltBlockHeight

impl Pod for AltBlockHeight

impl StructuralPartialEq for AltBlockHeight
