Struct postgres_parser::nodes::A_Indirection

pub struct A_Indirection {
    pub arg: Option<Box<Node>>,
    pub indirection: Option<Vec<Node>>,
}

A_Indirection select a field and/or array element from an expression

The indirection list can contain A_Indices nodes (representing subscripting), string Value nodes (representing field selection the string value is the name of the field to select), and A_Star nodes (representing selection of all fields of a composite type). For example, a complex selection operation like (foo).field1[42][7].field2 would be represented with a single A_Indirection node having a 4element indirection list.

Currently, A_Star must appear only as the last list element the grammar is responsible for enforcing this!

Fields

arg: Option<Box<Node>>

indirection: Option<Vec<Node>>
