Struct DatabaseUpdate

pub struct DatabaseUpdate<F>
where
    F: WebsocketFormat,
{
    pub tables: Vec<TableUpdate<F>>,
}

pub fn num_rows(&self) -> usize

Trait Implementations

impl<F> Clone for DatabaseUpdate<F>

where F: Clone + WebsocketFormat,

fn clone(&self) -> DatabaseUpdate<F>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<F> Debug for DatabaseUpdate<F>

where F: Debug + WebsocketFormat,

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

Formats the value using the given formatter.

impl<F> Default for DatabaseUpdate<F>

where F: Default + WebsocketFormat,

fn default() -> DatabaseUpdate<F>

Returns the “default value” for a type.

impl<'de, F> Deserialize<'de> for DatabaseUpdate<F>

where F: WebsocketFormat + Deserialize<'de>,

fn deserialize<D>( deserializer: D, ) -> Result<DatabaseUpdate<F>, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given deserializer.

impl<F> FromIterator<TableUpdate<F>> for DatabaseUpdate<F>

where F: WebsocketFormat,

fn from_iter<T>(iter: T) -> DatabaseUpdate<F>

where T: IntoIterator<Item = TableUpdate<F>>,

Creates a value from an iterator.

impl<F> Serialize for DatabaseUpdate<F>

where F: WebsocketFormat + Serialize,

fn serialize<S>( &self, __serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

impl<F> SpacetimeType for DatabaseUpdate<F>

where F: WebsocketFormat + SpacetimeType + 'static,

fn make_type<S>(__typespace: &mut S) -> AlgebraicType

where S: TypespaceBuilder,

Returns an AlgebraicType representing the type for Self in SATS and in the typing context in typespace. This is used by the automatic type registration system in Rust modules.
