Trait Implementations

impl Clone for ResultColumn

fn clone(&self) -> ResultColumn

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ResultColumn

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

Formats the value using the given formatter.

impl PartialEq for ResultColumn

fn eq(&self, other: &ResultColumn) -> 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 ToTokens for ResultColumn

fn to_tokens<S: TokenStream>(&self, s: &mut S) -> Result<(), S::Error>

Send token(s) to the specified stream

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

Format AST node
