Struct FunctionNode

#[non_exhaustive]
pub struct FunctionNode {
    pub name: String,
    pub arguments: Vec<Expression>,
    /* private fields */
}

A node representing a function call

E.g. SUBSTR('A', 1, 2)

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.

name: String

The name of the function to execute

arguments: Vec<Expression>

The arguments to the function

Implementations

impl FunctionNode

pub fn new(name: impl ToString, arguments: impl Expressions) -> Self

Create a new node

pub fn name(&self) -> &str

The name of the function to execute

pub fn iter(&self) -> impl Iterator<Item = &Expression>

An iterator over the arguments of the function

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

Visit this node with the provided visitor

Trait Implementations

impl Clone for FunctionNode

fn clone(&self) -> FunctionNode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl From<FunctionNode> for Expression

fn from(node: FunctionNode) -> Expression

Converts to this type from the input type.

impl PartialEq for FunctionNode

fn eq(&self, other: &FunctionNode) -> 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 Eq for FunctionNode
