Struct quaint::connector::ResultSet

pub struct ResultSet { /* private fields */ }

Encapsulates a set of results and their respective column names.

Implementations

impl ResultSet

pub fn new(names: Vec<String>, rows: Vec<Vec<Value<'static>>>) -> Self

Creates a new instance, bound to the given column names and result rows.

pub fn set_last_insert_id(&mut self, id: u64)

pub fn last_insert_id(&self) -> Option<u64>

The last id inserted, if available. Only works on certain databases and if using an auto-increment ids.

pub fn columns(&self) -> &Vec<String>

An iterator of column names.

pub fn len(&self) -> usize

Returns the number of rows in the ResultSet.

pub fn is_empty(&self) -> bool

Returns true if the ResultSet contains no rows.

pub fn first(&self) -> Option<ResultRowRef<'_>>

Returns the first row of the ResultSet, or None if the set is empty.

pub fn get(&self, index: usize) -> Option<ResultRowRef<'_>>

Returns a reference to a row in a given position.

pub fn into_single(self) -> Result<ResultRow>

Takes the first row if existing, otherwise returns error.

Trait Implementations

impl Debug for ResultSet

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

Formats the value using the given formatter.

impl Default for ResultSet

fn default() -> ResultSet

Returns the “default value” for a type.

impl From<ResultSet> for Value

fn from(result_set: ResultSet) -> Self

Converts to this type from the input type.

impl IntoIterator for ResultSet

type Item = ResultRow

type IntoIter = ResultSetIterator

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
