Struct CteChain 

pub struct CteChain { /* private fields */ }

A common table expression under construction.

with("recent", body) is already a complete mod; the methods add the optional parts of PostgreSQL’s with_query production.

Implementations

impl CteChain

pub fn columns( self, columns: impl IntoIterator<Item = impl Into<Cow<'static, str>>>, ) -> CteChain

Name the CTE’s output columns: WITH "c" ("a", "b") AS (…).

pub fn materialized(self) -> CteChain

AS MATERIALIZED (…) — compute it once, whatever the planner would prefer.

pub fn not_materialized(self) -> CteChain

AS NOT MATERIALIZED (…) — allow it to be folded into the outer query.

pub fn search_breadth( self, set: impl Into<Cow<'static, str>>, columns: impl IntoIterator<Item = impl Into<Cow<'static, str>>>, ) -> CteChain

SEARCH BREADTH FIRST BY cols SET col.

pub fn search_depth( self, set: impl Into<Cow<'static, str>>, columns: impl IntoIterator<Item = impl Into<Cow<'static, str>>>, ) -> CteChain

SEARCH DEPTH FIRST BY cols SET col.

bob’s SearchBreadth sets SearchDepth too, which is a copy-paste slip; the two are distinct here.

pub fn cycle( self, set: impl Into<Cow<'static, str>>, using: impl Into<Cow<'static, str>>, columns: impl IntoIterator<Item = impl Into<Cow<'static, str>>>, ) -> CteChain

CYCLE cols SET mark USING path.

pub fn cycle_value(self, to: impl IntoExpr, default: impl IntoExpr) -> CteChain

… SET mark TO value DEFAULT value USING ….

Both halves at once, because the grammar spells them as one optional group. PostgreSQL requires constants here — TO AexprConst DEFAULT AexprConst — so use s or raw, never arg.
