Struct UpdateDataModel 

pub struct UpdateDataModel {
    pub surface_id: String,
    pub path: String,
    pub value: Value,
}

Payload of an updateDataModel message.

Upsert semantics: an existing path is replaced, a missing path is created, and a null value deletes the key.

Fields

surface_id: String

Surface whose data model is being updated.

path: String

JSON Pointer into the data model. Defaults to /, the whole model.

value: Value

The new value. null deletes the key at path.

Implementations

impl UpdateDataModel

pub fn apply(&self, model: &mut Value) -> Result<()>

Applies this update to a surface data model in place.

• path of / or "" replaces the whole model (or clears it to null).
• Missing intermediate objects are created.
• A null value removes the key (or, in an array, sets the slot to null so the array keeps its length, per spec).

Errors

Returns Error::Pointer when the pointer is malformed, when it walks through a scalar, or when an array index is not a number within bounds.

Trait Implementations

impl Clone for UpdateDataModel

fn clone(&self) -> UpdateDataModel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UpdateDataModel

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for UpdateDataModel

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for UpdateDataModel

fn eq(&self, other: &UpdateDataModel) -> 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.

impl Serialize for UpdateDataModel

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
