Implementations§

§

impl<'a, Cn, Cl, PrimaryKey> List<'a, Cn, Cl, PrimaryKey>where Cl: SerializedCollection, Cn: Connection, PrimaryKey: KeyEncoding<<Cl as Collection>::PrimaryKey> + PartialEq<PrimaryKey> + 'a + ?Sized, <Cl as Collection>::PrimaryKey: Borrow<PrimaryKey> + PartialEq<PrimaryKey>,

pub fn ascending(self) -> List<'a, Cn, Cl, PrimaryKey>

Lists documents by id in ascending order.

pub fn descending(self) -> List<'a, Cn, Cl, PrimaryKey>

Lists documents by id in descending order.

pub fn limit(self, maximum_results: u32) -> List<'a, Cn, Cl, PrimaryKey>

Sets the maximum number of results to return.

pub fn headers(self) -> Result<Vec<Header, Global>, Error>

Returns the list of document headers contained within the range.

println!(
    "Headers with id 42 or larger: {:?}",
    MyCollection::list(42.., db).headers()?
);
println!(
    "Headers in MyCollection: {:?}",
    MyCollection::all(db).headers()?
);

pub fn count(self) -> Result<u64, Error>

Returns the number of documents contained within the range.

Order and limit are ignored if they were set.

println!(
    "Number of documents with id 42 or larger: {}",
    MyCollection::list(42.., db).count()?
);
println!(
    "Number of documents in MyCollection: {}",
    MyCollection::all(db).count()?
);

pub fn query(self) -> Result<Vec<CollectionDocument<Cl>, Global>, Error>

Retrieves the list of documents, using the configured options.
