Struct Response 

pub struct Response {
    pub command_tag: String,
    pub columns: Vec<Column>,
    pub rows: Vec<Vec<Value>>,
    pub truncated: bool,
}

Unary response from db query.

Fields

command_tag: String

Wire-protocol-style command tag — e.g. "SELECT 5", "SHOW 1", "EXPLAIN 12", "SET 0". Synthesized from {leading_keyword} {row_count} since sqlx 0.8 doesn’t expose the wire-protocol CommandComplete tag; close enough for telemetry / display.

columns: Vec<Column>

Result columns in select-list order. Empty for no-row statements (SET / LISTEN / DO).

rows: Vec<Vec<Value>>

One inner Vec per row, length matches columns.len(). Each cell is a serde_json::Value produced by the CLI’s per-cell pg_value_to_json decoder. Common type encodings: text/uuid/timestamps as JSON String, numeric as String (preserving precision), bytea as base64 String, json/jsonb passthrough as Value, arrays recurse. Empty when the statement returns no rows (no-row command OR a SELECT with no matches).

truncated: bool

Always false in the current design. Reserved on the wire so a future “soft truncation” mode can be added without a shape break.

Trait Implementations

impl Clone for Response

fn clone(&self) -> Response

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CommandResponse for Response

Available on crate feature mcp only.

fn into_mcp(self) -> McpResponseItem

impl Debug for Response

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Response

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for Response

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for Response

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
