pub struct Target {
    pub expr: Expr,
    pub alias: Option<String>,
}

The expression to select.

alias: Option<String>

Optional alias (AS name).

Implementations

impl Target

pub const fn new(expr: Expr) -> Self

Create a new target from an expression.

pub fn with_alias(expr: Expr, alias: impl Into<String>) -> Self

Create a target with an alias.

Trait Implementations

impl Clone for Target

fn clone(&self) -> Target

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Target

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

Formats the value using the given formatter.

impl PartialEq for Target

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