Struct bonsaidb_core::document::CollectionDocument

pub struct CollectionDocument<C> where
    C: SerializedCollection,  {
    pub header: Header,
    pub contents: C::Contents,
}

A document with serializable contents.

Fields

header: Header

The header of the document, which contains the id and Revision.

contents: C::Contents

The document’s contents.

Implementations

impl<C> CollectionDocument<C> where
    C: SerializedCollection, 

pub async fn update<Cn: Connection>(
    &mut self,
    connection: &Cn
) -> Result<(), Error>

Stores the new value of contents in the document.

pub async fn modify<Cn: Connection, Modifier: FnMut(&mut Self) + Send + Sync>(
    &mut self,
    connection: &Cn,
    modifier: Modifier
) -> Result<(), Error>

Modifies self, automatically retrying the modification if the document has been updated on the server.

Data loss warning

If you’ve modified self before calling this function and a conflict occurs, all changes to self will be lost when the current document is fetched before retrying the process again. When you use this function, you should limit the edits to the value to within the modifier callback.

pub async fn delete<Cn: Connection>(&self, connection: &Cn) -> Result<(), Error>

Removes the document from the collection.

pub fn to_document(&self) -> Result<OwnedDocument, Error>

Converts this value to a serialized Document.

Methods from Deref<Target = Header>

pub fn emit(&self) -> Mappings<(), ()>

Creates a Map result with an empty key and value.

pub fn emit_key<K: for<'a> Key<'a>>(&self, key: K) -> Mappings<K, ()>

Creates a Map result with a key and an empty value.

pub fn emit_value<Value>(&self, value: Value) -> Mappings<(), Value>

Creates a Map result with value and an empty key.

pub fn emit_key_and_value<K: for<'a> Key<'a>, Value>(
    &self,
    key: K,
    value: Value
) -> Mappings<K, Value>

Creates a Map result with a key and value.
