Implementations§

impl ExplainExecutionNodeType

pub const fn as_str(self) -> &'static str

Return the stable string label used by explain renderers.

pub const fn layer_label(self) -> &'static str

Return the owning execution layer label for this node type.

Trait Implementations§

impl Clone for ExplainExecutionNodeType

fn clone(&self) -> ExplainExecutionNodeType

Returns a duplicate of the value. Read more

1.0.0 (const: unstable) · Source§

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

Performs copy-assignment from source. Read more

impl Debug for ExplainExecutionNodeType

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

Formats the value using the given formatter. Read more

impl PartialEq for ExplainExecutionNodeType

fn eq(&self, other: &ExplainExecutionNodeType) -> bool

Tests for self and other values to be equal, and is used by ==.

1.0.0 (const: unstable) · Source§

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
