Enum gapi_grpc::google::datastore::v1::mutation::Operation

pub enum Operation {
    Insert(Entity),
    Update(Entity),
    Upsert(Entity),
    Delete(Key),
}

The mutation operation.

For insert, update, and upsert:

• The entity’s key must not be reserved/read-only.
• No property in the entity may have a reserved name, not even a property in an entity in a value.
• No value in the entity may have meaning 18, not even a value in an entity in another value.

Variants

Insert(Entity)

The entity to insert. The entity must not already exist. The entity key’s final path element may be incomplete.

Update(Entity)

The entity to update. The entity must already exist. Must have a complete key path.

Upsert(Entity)

The entity to upsert. The entity may or may not already exist. The entity key’s final path element may be incomplete.

Delete(Key)

The key of the entity to delete. The entity may or may not already exist. Must have a complete key path and must not be reserved/read-only.

Trait Implementations

impl Clone for Operation

fn clone(&self) -> Operation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Operation

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

Formats the value using the given formatter.

impl PartialEq<Operation> for Operation

fn eq(&self, other: &Operation) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Operation) -> bool

This method tests for !=.
