Struct QueryResult 

#[non_exhaustive]
pub struct QueryResult {
    pub columns: Vec<Column>,
    pub rows: Vec<Row>,
    pub message: String,
    pub partial_result: bool,
    pub status: Option<Status>,
    /* private fields */
}

QueryResult contains the result of executing a single SQL statement.

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.

columns: Vec<Column>

List of columns included in the result. This also includes the data type of the column.

rows: Vec<Row>

Rows returned by the SQL statement.

message: String

Message related to the SQL execution result.

partial_result: bool

Set to true if the SQL execution’s result is truncated due to size limits or an error retrieving results.

status: Option<Status>

If results were truncated due to an error, details of that error.

Implementations

impl QueryResult

pub fn new() -> Self

pub fn set_columns<T, V>(self, v: T) -> Self

where T: IntoIterator<Item = V>, V: Into<Column>,

Sets the value of columns.

Example

use google_cloud_sql_v1::model::Column;
let x = QueryResult::new()
    .set_columns([
        Column::default()/* use setters */,
        Column::default()/* use (different) setters */,
    ]);

pub fn set_rows<T, V>(self, v: T) -> Self

where T: IntoIterator<Item = V>, V: Into<Row>,

Sets the value of rows.

Example

use google_cloud_sql_v1::model::Row;
let x = QueryResult::new()
    .set_rows([
        Row::default()/* use setters */,
        Row::default()/* use (different) setters */,
    ]);

pub fn set_message<T: Into<String>>(self, v: T) -> Self

Sets the value of message.

Example

let x = QueryResult::new().set_message("example");

pub fn set_partial_result<T: Into<bool>>(self, v: T) -> Self

Sets the value of partial_result.

Example

let x = QueryResult::new().set_partial_result(true);

pub fn set_status<T>(self, v: T) -> Self

where T: Into<Status>,

Sets the value of status.

Example

use rpc::model::Status;
let x = QueryResult::new().set_status(Status::default()/* use setters */);

pub fn set_or_clear_status<T>(self, v: Option<T>) -> Self

where T: Into<Status>,

Sets or clears the value of status.

Example

use rpc::model::Status;
let x = QueryResult::new().set_or_clear_status(Some(Status::default()/* use setters */));
let x = QueryResult::new().set_or_clear_status(None::<Status>);

Trait Implementations

impl Clone for QueryResult

fn clone(&self) -> QueryResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryResult

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

Formats the value using the given formatter.

impl Default for QueryResult

fn default() -> QueryResult

Returns the “default value” for a type.

impl Message for QueryResult

fn typename() -> &'static str

The typename of this message.

impl PartialEq for QueryResult

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