Struct ProjectionField 

pub struct ProjectionField {
    pub name: String,
    pub is_composite: bool,
}

A field in a SQL projection with type information.

Used by typed projection generators to choose the correct JSONB extraction operator: -> (preserves JSONB) for objects/arrays, ->> (text) for scalars.

Fields

name: String

GraphQL field name (camelCase).

is_composite: bool

Whether this field is a composite type (Object or List) that should be extracted as JSONB (->) rather than text (->>).

Implementations

impl ProjectionField

pub fn scalar(name: impl Into<String>) -> Self

Create a scalar projection field (uses ->> text extraction).

pub fn composite(name: impl Into<String>) -> Self

Create a composite (object/list) projection field (uses -> JSONB extraction).

Trait Implementations

impl Clone for ProjectionField

fn clone(&self) -> ProjectionField

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProjectionField

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

Formats the value using the given formatter.

impl From<String> for ProjectionField

fn from(name: String) -> Self

Converts to this type from the input type.

impl PartialEq for ProjectionField

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