Struct Cursor 

pub struct Cursor {
    pub updated_at: OffsetDateTime,
    pub id: MemoId,
}

Synchronization cursor: (updated_at, id). Stable across reindex because both components live in the memo file’s frontmatter (§5.3).

Fields

updated_at: OffsetDateTime

id: MemoId

Implementations

impl Cursor

pub fn parse(s: &str) -> Result<Self>

Parse a cursor from its JSON serialization. The cursor is serialized as {updated_at, id}; this parses that shape from a string.

pub fn sort_key(&self) -> (OffsetDateTime, MemoId)

Ordering used for pagination and export: newer (larger updated_at, then larger id) sorts first.

Trait Implementations

impl Clone for Cursor

fn clone(&self) -> Cursor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Cursor

impl Debug for Cursor

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Cursor

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

where __D: Deserializer<'de>,

impl Eq for Cursor

impl Ord for Cursor

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.

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Cursor

fn eq(&self, other: &Cursor) -> bool

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Cursor

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

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 Cursor

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
