Implementations

impl Select

pub fn select_names(&self) -> Vec<String>

return the column names selected does not return functions.

pub fn select_alias(&self) -> Vec<Identifier>

return the aliased column names. If the column is not aliased the base column name is returned. does not return functions.

Trait Implementations

impl Clone for Select

fn clone(&self) -> Select

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Select

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

Formats the value using the given formatter.

impl Display for Select

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

Formats the value using the given formatter.

impl PartialEq<Select> for Select

fn eq(&self, other: &Select) -> 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.
