Struct mithril_common::entities::BlockRange

pub struct BlockRange { /* private fields */ }

BlockRange for the Cardano chain

Implementations

impl BlockRange

pub const LENGTH: BlockRangeLength = 15u64

The length of the block range Important: this value should be updated with extreme care (probably with an era change) in order to avoid signing disruptions.

pub fn new(start: BlockNumber, end: BlockNumber) -> Self

BlockRange factory

pub fn try_add(&self, other: &BlockRange) -> StdResult<BlockRange>

Try to add two BlockRanges

pub fn start(number: BlockNumber) -> BlockNumber

Get the start of the block range that contains the given block number

pub fn all_block_ranges_in(interval: Range<BlockNumber>) -> BlockRangesSequence

Get all BlockRange strictly contained in the given interval

pub fn from_block_number(number: BlockNumber) -> Self

Create a BlockRange from a block number

Methods from Deref<Target = Range<u64>>

pub fn contains<U>(&self, item: &U) -> bool

where Idx: PartialOrd<U>, U: PartialOrd<Idx> + ?Sized,

Returns true if item is contained in the range.

Examples

assert!(!(3..5).contains(&2));
assert!( (3..5).contains(&3));
assert!( (3..5).contains(&4));
assert!(!(3..5).contains(&5));

assert!(!(3..3).contains(&3));
assert!(!(3..2).contains(&3));

assert!( (0.0..1.0).contains(&0.5));
assert!(!(0.0..1.0).contains(&f32::NAN));
assert!(!(0.0..f32::NAN).contains(&0.5));
assert!(!(f32::NAN..1.0).contains(&0.5));

pub fn is_empty(&self) -> bool

Returns true if the range contains no items.

Examples

assert!(!(3..5).is_empty());
assert!( (3..3).is_empty());
assert!( (3..2).is_empty());

The range is empty if either side is incomparable:

assert!(!(3.0..5.0).is_empty());
assert!( (3.0..f32::NAN).is_empty());
assert!( (f32::NAN..5.0).is_empty());

Trait Implementations

impl Clone for BlockRange

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BlockRange

Formats the value using the given formatter.

impl Deref for BlockRange

type Target = Range<u64>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'de> Deserialize<'de> for BlockRange

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for BlockRange

Formats the value using the given formatter.

impl From<BlockRange> for MKTreeNode

fn from(other: BlockRange) -> Self

Converts to this type from the input type.

impl From<Range<u64>> for BlockRange

fn from(other: Range<u64>) -> Self

Converts to this type from the input type.

impl Hash for BlockRange

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 BlockRange

fn cmp(&self, other: &Self) -> 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 + PartialOrd,

impl PartialEq for BlockRange

fn eq(&self, other: &BlockRange) -> 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.

impl PartialOrd for BlockRange

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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