Struct Query 

pub struct Query {
    pub kind_filter: Option<String>,
    pub tag_filter: Vec<String>,
    pub limit: Option<usize>,
    pub offset: usize,
}

A composable filter + pagination descriptor for store queries.

Build via the fluent API:

let q = Query::new()
    .kind("Atom::Source")
    .tag("layer:domain")
    .limit(20)
    .offset(40);

Fields

kind_filter: Option<String>

If set, only return entities whose kind string matches this value.

tag_filter: Vec<String>

All listed tags must be present on the entity (AND semantics).

limit: Option<usize>

Maximum number of items to return. None means no limit.

offset: usize

Number of matching items to skip before returning results.

Implementations

impl Query

pub fn new() -> Self

Create a new, unconstrained query.

pub fn kind(self, k: impl Into<String>) -> Self

Filter by entity kind (exact match).

pub fn tag(self, t: impl Into<String>) -> Self

Require a specific tag to be present on matching entities. Multiple calls accumulate (AND semantics).

pub fn limit(self, n: usize) -> Self

Maximum number of results to return.

pub fn offset(self, n: usize) -> Self

Number of matching items to skip (for pagination).

Trait Implementations

impl Clone for Query

fn clone(&self) -> Query

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Query

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

Formats the value using the given formatter.

impl Default for Query

fn default() -> Query

Returns the “default value” for a type.
