Enum OutputSyntax 

enum OutputSyntax {
    Implicit,
    Explicit,
}

How a relation header renders its output.

Variants

Implicit

Output columns are rendered as final visible output: => output_columns.

Explicit

Output columns are rendered as the direct output domain: +> columns, with |> order appended when an explicit emit mapping is present.

Trait Implementations

impl Clone for OutputSyntax

fn clone(&self) -> OutputSyntax

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OutputSyntax

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

Formats the value using the given formatter.

impl Default for OutputSyntax

fn default() -> OutputSyntax

Returns the “default value” for a type.

impl PartialEq for OutputSyntax

fn eq(&self, other: &OutputSyntax) -> 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 Copy for OutputSyntax

impl Eq for OutputSyntax
