Implementations

impl Collection

pub fn new(name: impl Into<String>) -> Self

Create a new collection.

pub fn with_schema(name: impl Into<String>, schema: Schema) -> Self

Create a collection with schema validation.

pub fn name(&self) -> &str

Get the collection name.

pub fn insert(&self, doc: Document) -> Result<DocumentId, CollectionError>

Insert a document.

pub fn insert_many( &self, docs: Vec<Document>, ) -> Result<Vec<DocumentId>, CollectionError>

Insert multiple documents.

pub fn get(&self, id: &DocumentId) -> Option<Document>

Get a document by ID.

pub fn update( &self, id: &DocumentId, doc: Document, ) -> Result<(), CollectionError>

Update a document.

pub fn delete(&self, id: &DocumentId) -> Result<Document, CollectionError>

Delete a document.

pub fn contains(&self, id: &DocumentId) -> bool

Check if a document exists.

pub fn count(&self) -> usize

Get the number of documents.

pub fn ids(&self) -> Vec<DocumentId>

Get all document IDs.

pub fn all(&self) -> Vec<Document>

Get all documents.

pub fn clear(&self)

Clear all documents.

pub fn find(&self, query: &Query) -> QueryResult

Find documents matching a query.

When possible, uses indexes on fields with Eq filters to narrow the candidate set before applying the full filter chain, reducing the number of documents scanned.

pub fn find_one(&self, query: &Query) -> Option<Document>

Find one document matching a query.

pub fn count_matching(&self, query: &Query) -> usize

Count documents matching a query.

pub fn create_index(&self, field: impl Into<String>, index_type: IndexType)

Create an index on a field.

pub fn drop_index(&self, field: &str)

Drop an index.

pub fn index_names(&self) -> Vec<String>

Get all index names.

pub fn set_schema(&mut self, schema: Schema)

Set the collection schema.

pub fn schema(&self) -> Option<&Schema>

Get the collection schema.

pub fn validate_all(&self) -> Vec<(DocumentId, ValidationResult)>

Validate all documents against the schema.
