Struct CollectionQuery 

pub struct CollectionQuery<'a, C> {
    pub ids: IdFilter<CollectionId>,
    pub name: TextFilter,
    pub source: TextFilter,
    /* private fields */
}

Available on crate feature utils only.

Fluent query builder for collections. Obtained via PostArchiverManager::collections().

Available filter fields

• ids: filter by a set of CollectionId values.
• name: LIKE fuzzy match on the collection name.
• source: LIKE fuzzy match on the source field.

Fields

ids: IdFilter<CollectionId>

name: TextFilter

source: TextFilter

Implementations

impl<'a, C: PostArchiverConnection> CollectionQuery<'a, C>

pub fn new(manager: &'a PostArchiverManager<C>) -> Self

Trait Implementations

impl<C: PostArchiverConnection> BaseFilter for CollectionQuery<'_, C>

type Based = Collection

fn update_sql<T: FromQuery<Based = Self::Based>>( &self, sql: RawSql<T>, ) -> RawSql<T>

Append all filter conditions held by this builder into sql and return the updated RawSql.

fn queryer(&self) -> &Queryer<'_, impl PostArchiverConnection>

Return a reference to the Queryer owned by this builder, used by the default count() impl.

fn count(&self) -> Result<u64>

impl<'a, C: Debug> Debug for CollectionQuery<'a, C>

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

Formats the value using the given formatter.

impl<C: PostArchiverConnection> Query for CollectionQuery<'_, C>

type Wrapper<T> = Vec<T>

The wrapper type for query results. For most builders this is Vec<T>; when wrapped by WithTotal it becomes Totalled<Vec<T>>.

type Based = Collection

The database table type this query targets.

fn query_with_context<T: FromQuery<Based = Self::Based>>( self, sql: RawSql<T>, ) -> Result<Self::Wrapper<T>>

Execute the query with an externally supplied RawSql context (typically threaded through decorator layers).

fn query<T: FromQuery<Based = Self::Based>>(self) -> Result<Self::Wrapper<T>>

Execute the query with a default empty RawSql context, returning all matching results.

impl<C> Sortable for CollectionQuery<'_, C>

type SortField = CollectionSort

The sortable field enum type, defined in each sub-module by impl_sortable!.

fn sort( self, field: Self::SortField, dir: SortDir, ) -> Sorted<Self, Self::SortField>

Sort by the given field and direction, returning Sorted<Self, SortField>.

fn sort_random(self) -> Sorted<Self, Random>

Sort results randomly using ORDER BY RANDOM().
