Struct Cursor 

pub struct Cursor {
    pub value: String,
    pub timestamp: Option<i64>,
}

Cursor for cursor-based pagination (more efficient for large datasets).

Fields

value: String

Opaque cursor value (typically base64-encoded position data).

timestamp: Option<i64>

Optional timestamp for time-based cursors.

Implementations

impl Cursor

pub fn new(value: impl Into<String>) -> Self

Create a new cursor from a value.

pub fn with_timestamp(value: impl Into<String>, timestamp: i64) -> Self

Create a cursor with a timestamp.

pub fn from_id(id: &Uuid) -> Self

Create a cursor from an ID (encodes as base64).

pub fn from_timestamp(timestamp: i64) -> Self

Create a cursor from a timestamp.

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 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>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Cursor

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