Trait Implementations

impl<'ex, T: Clone> Clone for SqlExpr<'ex, T>

fn clone(&self) -> SqlExpr<'ex, T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'ex, T: Debug> Debug for SqlExpr<'ex, T>

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

Formats the value using the given formatter.

impl<'ex, T: Ord> Ord for SqlExpr<'ex, T>

fn cmp(&self, other: &SqlExpr<'ex, T>) -> Ordering

This method returns an Ordering between self and other.

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

where Self: Sized,

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<'ex, T: PartialEq> PartialEq for SqlExpr<'ex, T>

fn eq(&self, other: &SqlExpr<'ex, T>) -> 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<'ex, T: PartialOrd> PartialOrd for SqlExpr<'ex, T>

fn partial_cmp(&self, other: &SqlExpr<'ex, T>) -> 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.
