Implementations

impl Condition

pub fn and<R>(self, right: R) -> Selfwhere R: Into<Condition>,

A logical AND operation

pub fn or<R>(self, right: R) -> Selfwhere R: Into<Condition>,

A logical OR operation

pub fn not(self) -> Self

A logical NOT operation

pub fn parenthesize(self) -> Self

Wraps a condition in parentheses. For example, a < b AND c > d becomes (a < b AND c > d).

Trait Implementations

impl Clone for Condition

fn clone(&self) -> Condition

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Condition

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

Formats the value using the given formatter.

impl Display for Condition

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

Formats the value using the given formatter.

impl From<And> for Condition

fn from(condition: And) -> Self

Converts to this type from the input type.

impl From<AttributeExists> for Condition

fn from(condition: AttributeExists) -> Self

Converts to this type from the input type.

impl From<AttributeNotExists> for Condition

fn from(condition: AttributeNotExists) -> Self

Converts to this type from the input type.

impl From<AttributeType> for Condition

fn from(condition: AttributeType) -> Self

Converts to this type from the input type.

impl From<BeginsWith> for Condition

fn from(condition: BeginsWith) -> Self

Converts to this type from the input type.

impl From<Between> for Condition

fn from(condition: Between) -> Self

Converts to this type from the input type.

impl From<Comparison> for Condition

fn from(condition: Comparison) -> Self

Converts to this type from the input type.

impl From<Condition> for String

fn from(condition: Condition) -> Self

Converts to this type from the input type.

impl From<Contains> for Condition

fn from(condition: Contains) -> Self

Converts to this type from the input type.

impl From<In> for Condition

fn from(condition: In) -> Self

Converts to this type from the input type.

impl From<Not> for Condition

fn from(condition: Not) -> Self

Converts to this type from the input type.

impl From<Or> for Condition

fn from(condition: Or) -> Self

Converts to this type from the input type.

impl From<Parenthetical> for Condition

fn from(condition: Parenthetical) -> Self

Converts to this type from the input type.

impl Hash for Condition

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

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 Not for Condition

fn not(self) -> Self::Output

A logical NOT operation

type Output = Condition

The resulting type after applying the ! operator.

impl PartialEq for Condition

fn eq(&self, other: &Condition) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for Condition
