Enum UpdateMode 

pub enum UpdateMode {
    Merge,
    Replace,
}

Update semantics for Store::update.

• Merge (default): RFC 7396 shallow merge. Absent fields are preserved from the stored row. A null patch value deletes the field when required = false; it returns a MiniAppError::Validation error when required = true. A full schema validation runs on the merged result before persisting.
• Replace: Full replacement — identical to the pre-breaking-change default behavior. The stored row is overwritten byte-for-byte with the supplied value after schema validation.

Variants

Merge

RFC 7396 shallow merge (default).

Replace

Full replacement (legacy behavior).

Trait Implementations

impl Clone for UpdateMode

fn clone(&self) -> UpdateMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for UpdateMode

impl Debug for UpdateMode

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

Formats the value using the given formatter.

impl Default for UpdateMode

fn default() -> UpdateMode

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for UpdateMode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for UpdateMode

impl JsonSchema for UpdateMode

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for UpdateMode

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

Tests for self and other values to be equal, and is used by ==.

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

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