Implementations

impl SqlTransform

pub fn as_super_mut(&mut self) -> Option<&mut Transform>

Optionally returns mutable references to the inner fields if this is a SqlTransform::Super, otherwise None

pub fn as_super(&self) -> Option<&Transform>

Optionally returns references to the inner fields if this is a SqlTransform::Super, otherwise None

pub fn into_super(self) -> Result<Transform, Self>

Returns the inner fields if this is a SqlTransform::Super, otherwise returns back the enum in the Err case of the result

pub fn is_distinct(&self) -> bool

Returns true if this is a SqlTransform::Distinct, otherwise false

pub fn as_except_mut(&mut self) -> Option<(&mut TableRef, &mut bool)>

Optionally returns mutable references to the inner fields if this is a SqlTransform::Except, otherwise None

pub fn as_except(&self) -> Option<(&TableRef, &bool)>

Optionally returns references to the inner fields if this is a SqlTransform::Except, otherwise None

pub fn into_except(self) -> Result<(TableRef, bool), Self>
