A PL/SQL expression node.

The syntactic expression projection — binary ops, function / procedure calls, cursor + attribute references, literals, bind / substitution placeholders. One step before plsql_ir::Expr (the semantic IR). Unknown satisfies R13.

Every variant carries a span (Spanned invariant).

Variants

Literal

A literal (number / string / NULL / TRUE / FALSE), kept verbatim so the IR can re-classify precisely.

Fields

text: String

span: Span

Name

A dotted name reference (a, pkg.fn, t.col%TYPE, c%ROWTYPE, :new.id).

Fields

path: String

span: Span

Bind

Bind placeholder (:1, :name).

Fields

name: String

span: Span

Substitution

Substitution variable (&v, &&v).

Fields

name: String

sticky: bool

span: Span

Call

A call callee(<args-text>) — args kept as raw text for the IR layer to split + recurse.

Fields

callee: String

args_text: String

span: Span

Binary

Binary op at the top level. Operand slices are raw text.

Fields

op: String

lhs_text: String

rhs_text: String

span: Span

Unary

Unary op (NOT / - / +).

Fields

op: String

operand_text: String

span: Span

Unknown

An expression the backend could not classify (R13).

Fields

text: String

span: Span

Trait Implementations

impl Clone for AstExpr

fn clone(&self) -> AstExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AstExpr

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AstExpr

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for AstExpr

impl PartialEq for AstExpr

fn eq(&self, other: &AstExpr) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for AstExpr

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Spanned for AstExpr

fn span(&self) -> Span

The source span of this AST node.
