Enum CteBlock

pub enum CteBlock<T: AstInfo> {
    Simple(Vec<Cte<T>>),
    MutuallyRecursive(MutRecBlock<T>),
}

A block of common table expressions (CTEs).

The block can either be entirely “simple” (traditional SQL WITH block), or “mutually recursive”, which introduce their bindings before the block and may result in mutually recursive definitions.

Variants

Simple(Vec<Cte<T>>)

MutuallyRecursive(MutRecBlock<T>)

Implementations

impl<T: AstInfo> CteBlock<T>

pub fn empty() -> Self

Returns an empty (simple) CTE block.

pub fn is_empty(&self) -> bool

True if there are no bindings in the block.

pub fn bound_identifiers(&self) -> impl Iterator<Item = &Ident>

Iterates through the identifiers used in bindings.

impl<T: Ord + AstInfo> Ord for CteBlock<T>

fn cmp(&self, other: &CteBlock<T>) -> Ordering

This method returns an Ordering between self and other.
