Implementations

impl PruneSegment

pub const fn bitflag_encoded_bytes() -> usize

Used bytes by [PruneSegmentFlags]

impl PruneSegment

pub const fn min_blocks(&self, purpose: PrunePurpose) -> u64

Returns minimum number of blocks to left in the database for this segment.

Trait Implementations

impl Clone for PruneSegment

fn clone(&self) -> PruneSegment

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Compact for PruneSegment

fn to_compact<B>(&self, buf: &mut B) -> usize

where B: BufMut + AsMut<[u8]>,

Takes a buffer which can be written to. Ideally, it returns the length written to.

fn from_compact(buf: &[u8], len: usize) -> (PruneSegment, &[u8])

Takes a buffer which can be read from. Returns the object and buf with its internal cursor advanced (eg..advance(len)).

fn specialized_to_compact<B>(&self, buf: &mut B) -> usize

where B: BufMut + AsMut<[u8]>,

“Optional”: If there’s no good reason to use it, don’t.

fn specialized_from_compact(buf: &[u8], len: usize) -> (Self, &[u8])

“Optional”: If there’s no good reason to use it, don’t.

impl Debug for PruneSegment

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

Formats the value using the given formatter.

impl Decode for PruneSegment

fn decode<B>(value: B) -> Result<PruneSegment, DatabaseError>

where B: AsRef<[u8]>,

Decodes data coming from the database.

impl<'de> Deserialize<'de> for PruneSegment

fn deserialize<__D>( __deserializer: __D, ) -> Result<PruneSegment, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for PruneSegment

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

Formats the value using the given formatter.

impl Encode for PruneSegment

type Encoded = [u8; 1]

Encoded type.

fn encode(self) -> <PruneSegment as Encode>::Encoded

Encodes data going into the database.

impl Hash for PruneSegment

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 PruneSegment

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

Restrict a value to a certain interval.

impl PartialEq for PruneSegment

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

fn partial_cmp(&self, other: &PruneSegment) -> 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 PruneSegment

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for PruneSegment

impl Eq for PruneSegment

impl StructuralPartialEq for PruneSegment

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
