Trait Implementations

impl Clone for CoalesceExpr

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CoalesceExpr

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

Formats the value using the given formatter.

impl Default for CoalesceExpr

fn default() -> Self

Returns the “default value” for a type.

impl Equal for CoalesceExpr

fn equal(&self, other: &Self) -> bool

The two values are equal, without a look at the locations.

impl From<CoalesceExpr> for Node

fn from(node: CoalesceExpr) -> Node

Converts to this type from the input type.

impl NodeType for CoalesceExpr

fn into_node(self: Box<Self>) -> Node

The node of this type as a Node.

fn from_node(node: Node) -> Result<Box<Self>, Node>

The node as this type, or the node back when it has another type.

fn peek(node: &Node) -> Option<&Self>

The node as this type, or None.

fn peek_mut(node: &mut Node) -> Option<&mut Self>

The node as this type, or None.

impl Out for CoalesceExpr

fn out(&self, s: &mut String)

Writes the name of the node type and its fields, without the braces.

fn fields(&self, s: &mut String, prefix: &str)

Writes the fields only, each name with prefix before it. A node type that is the first field of another, as CreateStmt is in CreateForeignTableStmt, writes its fields so.

impl PartialEq for CoalesceExpr

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

Equality operator ==.

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

Inequality operator !=.
