Struct PLpgSQLVar 

pub struct PLpgSQLVar {
    pub name: String,
    pub type_name: String,
    pub type_reference: Option<RoutineColumnTypeReference>,
    pub default: Option<Expr>,
    pub constant: bool,
    pub not_null: bool,
    pub cursor: Option<PLpgSQLCursor>,
    pub lineno: Option<i64>,
}

Scalar PL/pgSQL variable (declared variable, parameter, loop counter, or an internal compiler temporary).

Fields

name: String

type_name: String

Normalized type name (integer, text, …). The engine resolves catalog-backed references such as %TYPE before execution.

type_reference: Option<RoutineColumnTypeReference>

Exact relation-column identity emitted by the PL/pgSQL parser for a table-backed %TYPE declaration.

default: Option<Expr>

constant: bool

not_null: bool

cursor: Option<PLpgSQLCursor>

Definition of a bound cursor declared with CURSOR (...) FOR query.

lineno: Option<i64>

Source line of the declaration; used to disambiguate loop variables that shadow outer names.
