Struct postgres_parser::sys::RangeFunction

#[repr(C)]pub struct RangeFunction {
    pub type_: NodeTag,
    pub lateral: bool,

}

RangeFunction function call appearing in a FROM clause

functions is a List because we use this to represent the construct ROWS FROM(func1(...), func2(...), ...). Each element of this list is a twoelement sublist, the first element being the untransformed function call tree, and the second element being a possiblyempty list of ColumnDef nodes representing any columndef list attached to that function within the ROWS FROM() syntax.

alias and coldeflist represent any alias and/or columndef list attached at the top level. (We disallow coldeflist appearing both here and perfunction, but that's checked in parse analysis, not by the grammar.)

Fields

type_: NodeTag

lateral: bool

ordinality: bool

does it have LATERAL prefix?

is_rowsfrom: bool

does it have WITH ORDINALITY suffix?

functions: *mut List

is result of ROWS FROM() syntax?

alias: *mut Alias

perfunction information, see above

coldeflist: *mut List

table alias & optional column aliases
