Overwrite Modes

Variants

Ignore

If a document with the specified _key value exists already, nothing will be done and no write operation will be carried out. The insert operation will return success in this case. This mode does not support returning the old document version using return_old. When using return_new, None will be returned in case the document already existed.

Update

If a document with the specified _key value exists already, it will be patched (partially updated) with the specified document value. The overwrite_mode can be further controlled via the keep_null and merge_objects configuration.

Replace

If a document with the specified _key value exists already, it will be overwritten with the specified document value. This mode will also be used when no overwrite_mode is specified but the overwrite flag is set to true.

Conflict

If a document with the specified _key value exists already, return a unique constraint violation error so that the insert operation fails. This is also the default behavior in case the overwrite_mode is not set, and the overwrite flag is false or not set either.

Trait Implementations

impl Clone for OverwriteMode

fn clone(&self) -> OverwriteMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OverwriteMode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for OverwriteMode

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>where
    D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for OverwriteMode

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

Formats the value using the given formatter.

impl From<OverwriteMode> for String

Example

let mode: String = OverwriteMode::Ignore.into();

fn from(mode: OverwriteMode) -> String

Example

let mode: String = OverwriteMode::Ignore.into();

impl PartialEq<OverwriteMode> for OverwriteMode

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for OverwriteMode

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

Serialize this value into the given Serde serializer.
