Struct OutColumn 

pub struct OutColumn {
    pub name: String,
    pub type_name: String,
    pub is_enum: bool,
}

A single output column of a PostgreSQL function’s result row.

Populated from either the OUT/TABLE parameters of a RETURNS TABLE(…) function or the attributes of a composite RETURNS <type> — both are how FraiseQL mutation functions declare the row the server decodes into MutationResponse.

Fields

name: String

Column name as it appears in the result row (matched against the MutationResponse field names).

type_name: String

format_type rendering of the column type (e.g. "boolean", "jsonb", "text[]", "app.mutation_error_class").

is_enum: bool

Whether the column type is a PostgreSQL enum (pg_type.typtype = 'e'). Mutation functions legitimately type error_class as either text or a project-specific enum, so the contract check accepts both.

Trait Implementations

impl Clone for OutColumn

fn clone(&self) -> OutColumn

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OutColumn

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

Formats the value using the given formatter.

impl Eq for OutColumn

impl PartialEq for OutColumn

fn eq(&self, other: &OutColumn) -> 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.
