Trait Implementations

impl Clone for Statement

fn clone(&self) -> Statement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Statement

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

Formats the value using the given formatter.

impl Display for Statement

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

Formats a SQL statement with support for pretty printing.

When using the alternate flag ({:#}), the statement will be formatted with proper indentation and line breaks. For example:

let sql = "SELECT a, b FROM table_1";
let ast = Parser::parse_sql(&GenericDialect, sql).unwrap();

// Regular formatting
assert_eq!(format!("{}", ast[0]), "SELECT a, b FROM table_1");

// Pretty printing
assert_eq!(format!("{:#}", ast[0]),
r#"SELECT
  a,
  b
FROM
  table_1"#);

impl From<Set> for Statement

Convert a Set into a Statement. Convenience function, instead of writing Statement::Set(Set::Set...{...})

fn from(set: Set) -> Statement

Converts to this type from the input type.

impl Hash for Statement

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Statement

fn cmp(&self, other: &Statement) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Statement

fn eq(&self, other: &Statement) -> 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 PartialOrd for Statement

fn partial_cmp(&self, other: &Statement) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
