A user-defined function (SQL or PL/pgSQL).

Fields

qname: QualifiedName

Schema-qualified function name.

args: Vec<FunctionArg>

Declared argument list (all modes).

arg_types_normalized: NormalizedArgTypes

Normalized identity hash over IN/INOUT/VARIADIC args only.

return_type: ReturnType

Return type.

language: FunctionLanguage

Implementation language.

body: NormalizedBody

Canonicalized function body.

body_dependencies: Vec<DepEdge>

Dependency edges extracted from the function body AST.

Filled by the T4 PL/pgSQL body parser and the T6 AST resolution pass. Empty until those passes run.

volatility: Volatility

Volatility category.

strict: bool

Whether the function returns NULL immediately for any NULL input.

security: SecurityMode

Security context (INVOKER or DEFINER).

parallel: ParallelSafety

Parallel safety classification.

leakproof: bool

Whether the function is marked LEAKPROOF.

cost: Option<f32>

Estimated per-call cost (units: sequential page fetches).

rows: Option<f32>

Estimated rows returned per call (for set-returning functions).

comment: Option<String>

Optional COMMENT ON FUNCTION text.

owner: Option<Identifier>

Object owner. None = unmanaged (the differ ignores ownership). Some(role) = managed: diff emits ALTER FUNCTION ... OWNER TO role.

grants: Vec<Grant>

Grants on this object. Empty = no grants. Canonicalized.

Trait Implementations

impl Clone for Function

fn clone(&self) -> Function

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Function

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Function

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Function

impl Equiv for Function

fn differences(&self, other: &Self) -> Vec<Difference>

List the differences between self and other. Empty list = equivalent.

fn canonical_eq(&self, other: &Self) -> bool

Convenience: true iff self.differences(other).is_empty().

impl Hash for Function

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

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Function

fn eq(&self, other: &Self) -> 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 Function

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
