Enum DoArg 

pub enum DoArg {
    Body {
        body: Literal,
        meta: Meta,
    },
    Language {
        name: LanguageName,
        meta: Meta,
    },
}

One item of a DoStatement’s dostmt_opt_list — a body string or a LANGUAGE clause. The two forms and their source order round-trip, so the parser records each as written rather than folding them into a canonical { language, body } pair.

Variants

Body

An inline-body Sconst item — PostgreSQL’s makeDefElem("as", …). The body is the opaque source Literal (kept, not re-parsed, like FunctionOption::As); there is no AS keyword in the DO syntax, so the variant is named for the block body it carries.

Fields

body: Literal

Statement or query body governed by this node.

meta: Meta

Source location and node identity.

Language

A LANGUAGE <name> item — PostgreSQL’s makeDefElem("language", …). The name is a NonReservedWord_or_Sconst (LanguageName): a bare word or a string constant, as in the CREATE FUNCTION LANGUAGE clause. A reserved word (a bit/hex/national string constant, since those are not Sconst) is the syntax error PostgreSQL reports.

Fields

name: LanguageName

Name referenced by this syntax.

meta: Meta

Source location and node identity.

Trait Implementations

impl Clone for DoArg

fn clone(&self) -> DoArg

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DoArg

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DoArg

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

Deserialize this value from the given Serde deserializer.

impl Eq for DoArg

impl Hash for DoArg

fn hash<__H: Hasher>(&self, state: &mut __H)
