Struct EventCursor 

pub struct EventCursor(/* private fields */);

Cursor for pagination in event queries.

The cursor represents the ID of an event and is used for pagination. It can be parsed from a string representation of an integer.

Note: Uses u64 internally, but Postgres BIGINT is signed (i64). sea_query/sqlx binds u64 values, which works correctly as long as IDs stay within i64::MAX (~9.2 quintillion). Since event IDs are auto-incrementing from 1, this is not a practical concern.

Implementations

impl EventCursor

pub fn new(id: u64) -> Self

Create a new cursor from an event ID.

pub fn id(&self) -> u64

Get the underlying ID value.

Trait Implementations

impl Clone for EventCursor

fn clone(&self) -> EventCursor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for EventCursor

impl Debug for EventCursor

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

Formats the value using the given formatter.

impl Display for EventCursor

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

Formats the value using the given formatter.

impl Eq for EventCursor

impl From<u64> for EventCursor

fn from(id: u64) -> Self

Converts to this type from the input type.

impl FromStr for EventCursor

type Err = ParseIntError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Ord for EventCursor

fn cmp(&self, other: &EventCursor) -> 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 PartialEq for EventCursor

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

fn partial_cmp(&self, other: &EventCursor) -> 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 StructuralPartialEq for EventCursor

impl TryFrom<&str> for EventCursor

type Error = ParseIntError

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<String> for EventCursor

type Error = ParseIntError

The type returned in the event of a conversion error.

fn try_from(s: String) -> Result<Self, Self::Error>

Performs the conversion.
