Struct ChangesResponse 

pub struct ChangesResponse {
    pub changes: Vec<Change>,
    pub next_cursor: String,
    pub has_more: bool,
}

The GET /changes response body (RFC-ACDP-0018 §5.2), CLOSED.

next_cursor is always present: the feed is a tail, so a consumer at the head keeps polling with it. has_more means entries past next_cursor were already committed; an empty changes with has_more: true is not the end of the feed.

Fields

changes: Vec<Change>

Matching, visible entries after since, ascending seq.

next_cursor: String

Opaque, durable cursor naming the position after the last entry scanned (§5.4).

has_more: bool

Entries past next_cursor were committed when the response was built; request again at once.

Implementations

impl ChangesResponse

pub fn from_value(value: &Value) -> Result<Self, AcdpError>

Parse a response, enforcing the closed schema, the cursor length bounds and strictly ascending seq. Failures are AcdpError::SchemaViolation.

pub fn validate(&self) -> Result<(), AcdpError>

The invariants serde does not enforce.
