Enum Where

pub enum Where<'a> {
    And(Vec<Where<'a>>),
    Or(Vec<Where<'a>>),
    Not(Box<Where<'a>>),
    Raw(SqlChunk<'a>),
    Empty,
}

An enum representing the WHERE clause of a query.

Variants

And(Vec<Where<'a>>)

A number of conditions joined by AND.

Or(Vec<Where<'a>>)

A number of conditions joined by OR.

Not(Box<Where<'a>>)

A negated condition.

Raw(SqlChunk<'a>)

A raw condition.

Empty

An empty WHERE clause.

Implementations

impl<'a> Where<'a>

pub fn and(self, other: Where<'a>) -> Where<'a>

Combine two conditions using AND.

You can also use the & operator.

pub fn or(self, other: Where<'a>) -> Where<'a>

Combine two conditions using OR.

You can also use the | operator.

Example

Where::new("id = ?", vec![&7])
    .or(Where::new("name = ?", vec![&"John"]))

Trait Implementations

impl<'a> BitAnd for Where<'a>

type Output = Where<'a>

The resulting type after applying the & operator.

fn bitand(self, other: Self) -> Self::Output

Performs the & operation.

impl<'a> BitOr for Where<'a>

type Output = Where<'a>

The resulting type after applying the | operator.

fn bitor(self, other: Self) -> Self::Output

Performs the | operation.

impl<'a> Default for Where<'a>

fn default() -> Self

Returns the “default value” for a type.

impl<'a> Not for Where<'a>

type Output = Where<'a>

The resulting type after applying the ! operator.

fn not(self) -> Self::Output

Performs the unary ! operation.
