Struct QueryOptions 

pub struct QueryOptions { /* private fields */ }

Options for configuring event queries.

Use the builder-style methods to configure direction and limits.

Example

use evidentsource_core::domain::{QueryDirection, QueryOptions};

// Default options (forward, no limit)
let opts = QueryOptions::default();

// Get first 100 events in reverse order
let opts = QueryOptions::new()
    .direction(QueryDirection::Reverse)
    .limit(100);

// Shorthand for reverse
let opts = QueryOptions::new().reverse().limit(50);

Implementations

impl QueryOptions

pub fn new() -> QueryOptions

Create new query options with default values.

pub fn direction(self, direction: QueryDirection) -> QueryOptions

Set the query direction.

pub fn forward(self) -> QueryOptions

Set the direction to forward (oldest to newest).

pub fn reverse(self) -> QueryOptions

Set the direction to reverse (newest to oldest).

pub fn limit(self, limit: u64) -> QueryOptions

Set the maximum number of results to return.

pub fn get_direction(&self) -> QueryDirection

Get the configured direction.

pub fn get_limit(&self) -> Option<u64>

Get the configured limit, if any.

Trait Implementations

impl Clone for QueryOptions

fn clone(&self) -> QueryOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryOptions

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

Formats the value using the given formatter.

impl Default for QueryOptions

fn default() -> QueryOptions

Returns the “default value” for a type.

impl Hash for QueryOptions

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 PartialEq for QueryOptions

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