Struct SeqData 

pub struct SeqData<D = Vec<u8>> { /* private fields */ }

Sequence-numbered non-marked data.

It is a subset of SeqMarked where data is always normal.

use seq_marked::SeqData;

let v1 = SeqData::new(1, "data");

Implementations

impl<D> SeqData<D>

pub fn new(seq: u64, data: D) -> Self

Creates normal value with sequence number.

pub fn map<U>(self, f: impl FnOnce(D) -> U) -> SeqData<U>

Transforms data D to U while preserving sequence and tombstone state.

Example

use seq_marked::SeqData;

let a = SeqData::new(1, "data");
let b = a.map(|x| x.len());
assert_eq!(b.data(), &4);

pub fn try_map<U, E>( self, f: impl FnOnce(D) -> Result<U, E>, ) -> Result<SeqData<U>, E>

pub fn as_ref(&self) -> SeqData<&D>

Creates reference to the data.

pub fn order_key(&self) -> SeqMarked<()>

Returns ordering key (sequence + tombstone state only).

pub fn internal_seq(&self) -> InternalSeq

Returns the sequence number for internal use, tombstone also has a seq.

pub fn user_seq(&self) -> u64

Returns the sequence number for application use, tombstone always has seq 0.

pub fn max(a: Self, b: Self) -> Self

Returns the maximum of two values.

pub fn max_ref<'l>(a: &'l Self, b: &'l Self) -> &'l Self

Returns the maximum of two values.

pub fn data(&self) -> &D

Returns reference to data if normal, None if tombstone.

pub fn into_data(self) -> D

Consumes and returns data if normal, None if tombstone.

pub fn into_parts(self) -> (u64, D)

pub fn display_with_debug(&self) -> impl Display + '_

where D: Debug,

Returns formatter for display using Debug trait.

Trait Implementations

impl<D: Clone> Clone for SeqData<D>

fn clone(&self) -> SeqData<D>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<D: Debug> Debug for SeqData<D>

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

Formats the value using the given formatter.

impl<M, T> From<SeqData<(Option<M>, T)>> for SeqV<M, T>

fn from(value: SeqData<(Option<M>, T)>) -> Self

Converts to this type from the input type.

impl<D> From<SeqData<D>> for SeqMarked<D>

fn from(value: SeqData<D>) -> Self

Converts to this type from the input type.

impl<M, T> From<SeqV<M, T>> for SeqData<(Option<M>, T)>

fn from(value: SeqV<M, T>) -> Self

Converts to this type from the input type.

impl<D: Ord> Ord for SeqData<D>

fn cmp(&self, other: &SeqData<D>) -> 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<D: PartialEq> PartialEq for SeqData<D>

fn eq(&self, other: &SeqData<D>) -> 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<D: PartialOrd> PartialOrd for SeqData<D>

fn partial_cmp(&self, other: &SeqData<D>) -> 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.
