Enum MeshDbResponse 

#[non_exhaustive]
pub enum MeshDbResponse {
    Batch {
        call_id: u64,
        batch: ResultBatch,
    },
    End {
        call_id: u64,
    },
    Error {
        call_id: u64,
        error: MeshError,
    },
}

Executor → caller streaming response.

Per call_id, the executor emits zero or more Batch messages followed by exactly one terminal (End or Error) — unless the terminal batch is coalesced via ResultBatch::last.

#[non_exhaustive] so phases C–F can add variants (e.g. a Progress heartbeat for long-running queries).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Batch

One chunk of rows. May be the last (see the final field on ResultBatch).

Fields

call_id: u64

Matches the originating request’s call_id.

batch: ResultBatch

The chunk.

End

Clean end of the response stream.

Fields

call_id: u64

Matches the originating request’s call_id.

Error

Terminal error. Carries the full MeshError so the caller can decide whether to resume (via the continuation token in PartialResult) or fail.

Fields

call_id: u64

Matches the originating request’s call_id.

error: MeshError

The error.

Trait Implementations

impl Clone for MeshDbResponse

fn clone(&self) -> MeshDbResponse

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MeshDbResponse

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MeshDbResponse

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MeshDbResponse

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
