Struct rets_expression::NotNode

#[non_exhaustive]
pub struct NotNode {
    pub expression: Box<Expression>,
    /* private fields */
}

A node representing the logical negation of an expression

E.g. .NOT. A

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.

expression: Box<Expression>

The negated expression

Implementations

impl NotNode

pub fn new(expression: impl Into<Box<Expression>>) -> Self

Create a new node

pub fn expression(&self) -> &Expression

The negated expression

pub fn accept(&mut self, visitor: &mut impl Visitor)

Visit this node with the provided visitor

Trait Implementations

impl Clone for NotNode

fn clone(&self) -> NotNode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl From<NotNode> for Expression

fn from(node: NotNode) -> Expression

Converts to this type from the input type.

impl PartialEq for NotNode

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