Struct WhenNode

pub struct WhenNode {
    pub childs: Vec<NodeType>,
    pub test: String,
}

Represents a when node in py_sql. It’s used as a child of a choose node to define a conditional block of SQL. The SQL block within when is executed if its test condition evaluates to true and no preceding when in the same choose was true.

Attributes

• test: The boolean expression to evaluate.

Example

PySQL syntax (inside a choose block):

choose:
  when test="type == 'A'":
    sql_for_type_A
  when test="type == 'B'":
    sql_for_type_B

Fields

childs: Vec<NodeType>

test: String

Trait Implementations

impl Clone for WhenNode

fn clone(&self) -> WhenNode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WhenNode

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

Formats the value using the given formatter.

impl Name for WhenNode

fn name() -> &'static str

impl PartialEq for WhenNode

fn eq(&self, other: &WhenNode) -> 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 WhenNode

fn as_html(&self) -> String
