Struct OpNode

#[non_exhaustive]
pub struct OpNode {
    pub left: Box<Expression>,
    pub op: ExpressionOp,
    pub right: Box<Expression>,
    /* private fields */
}

A node representing a binary operation

E.g. A + B

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

left: Box<Expression>

The expression on the left of the operation

op: ExpressionOp

The operation to perform

right: Box<Expression>

The expression on the left of the operation

Implementations

Trait Implementations

impl Clone for OpNode

fn clone(&self) -> OpNode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl From<OpNode> for Expression

fn from(node: OpNode) -> Expression

Converts to this type from the input type.

impl PartialEq for OpNode

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