Struct Values 

pub struct Values {
    pub rows: Vec<Expr>,
}

A VALUES clause: a set of row expressions.

Used as the source for INSERT statements and as a query body type that produces literal rows without reading from a table.

Examples

use toasty_core::stmt::{Values, Expr};

let values = Values::new(vec![Expr::null()]);
assert_eq!(values.rows.len(), 1);
assert!(!values.is_empty());

Fields

rows: Vec<Expr>

The row expressions. Each element is one row to insert or return.

Implementations

impl Values

pub fn new(rows: Vec<Expr>) -> Self

Creates a Values from a vector of row expressions.

pub fn is_empty(&self) -> bool

Returns true if there are no rows.

pub fn is_const(&self) -> bool

Returns true if all rows are constant expressions.

Trait Implementations

impl Clone for Values

fn clone(&self) -> Values

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Values

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

Formats the value using the given formatter.

impl Default for Values

fn default() -> Values

Returns the “default value” for a type.

impl From<Expr> for Values

fn from(value: Expr) -> Self

Converts to this type from the input type.

impl From<Values> for ExprSet

fn from(value: Values) -> Self

Converts to this type from the input type.

impl From<Values> for Query

fn from(value: Values) -> Self

Converts to this type from the input type.

impl PartialEq for Values

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