Struct mongodb::change_stream::event::UpdateDescription

#[non_exhaustive]
pub struct UpdateDescription {
    pub updated_fields: Document,
    pub removed_fields: Vec<String>,
    pub truncated_arrays: Option<Vec<TruncatedArray>>,
}

Describes which fields have been updated or removed from a document.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

updated_fields: Document

A Document containing key:value pairs of names of the fields that were changed, and the new value for those fields.

removed_fields: Vec<String>

An array of field names that were removed from the Document.

truncated_arrays: Option<Vec<TruncatedArray>>

Arrays that were truncated in the Document.

Trait Implementations

impl Debug for UpdateDescription

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for UpdateDescription

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

Deserialize this value from the given Serde deserializer.

impl PartialEq<UpdateDescription> for UpdateDescription

fn eq(&self, other: &UpdateDescription) -> 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 UpdateDescription

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

Serialize this value into the given Serde serializer.
