Struct ChooseNode

pub struct ChooseNode {
    pub when_nodes: Vec<NodeType>,
    pub otherwise_node: Option<Box<NodeType>>,
}

Represents a choose node in py_sql. It provides a way to conditionally execute different blocks of SQL, similar to a switch statement. It must contain one or more when child nodes and can optionally have an otherwise child node.

Example

PySQL syntax:

choose:
  when test="type == 'A'":
    sql_block_A
  when test="type == 'B'":
    sql_block_B
  otherwise:
    sql_block_default

Fields

when_nodes: Vec<NodeType>

otherwise_node: Option<Box<NodeType>>

Trait Implementations

impl Clone for ChooseNode

fn clone(&self) -> ChooseNode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ChooseNode

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

Formats the value using the given formatter.

impl Name for ChooseNode

fn name() -> &'static str

impl PartialEq for ChooseNode

fn eq(&self, other: &ChooseNode) -> 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 ToHtml for ChooseNode

fn as_html(&self) -> String
