Struct ExpandedComponentChange 

pub struct ExpandedComponentChange {
    pub op: ComponentOp,
    pub key: Option<Vec<u8>>,
    pub value: Option<Vec<u8>>,
}

A single per-element view of an incoming AppDataUpdate proposal.

Bytes components produce exactly one entry; collection components produce one entry per delta mutation. The op mirrors the ComponentOp field on a ComponentChange so the validator can call validate_component_write directly.

key is the TLS-encoded element key of a map mutation, which the self-owned policy and the DM registry exception read (PERM-027, PERM-026). It is None for scalars, for set mutations (whose value is the element), and for a whole-component Remove.

value is the new value bytes for an Insert or Update, and the element for a set Delete. It is None for a map Delete and a whole-component Remove.

Fields

op: ComponentOp

Whether this entry is an Insert, Update, or Delete.

key: Option<Vec<u8>>

The TLS-encoded map key, if this entry mutates a map element.

value: Option<Vec<u8>>

The new value bytes, or the removed set element.

Trait Implementations

impl Clone for ExpandedComponentChange

fn clone(&self) -> ExpandedComponentChange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExpandedComponentChange

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

Formats the value using the given formatter.

impl PartialEq for ExpandedComponentChange

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