Struct substrait_expr::helpers::schema::NamesOnlySchema

pub struct NamesOnlySchema {
    pub root: NamesOnlySchemaNode,
    /* private fields */
}

Represents a potentially nested schema where we only know the names and not the types of the fields.

The root of the schema is Vec<NamesOnlySchemaNode> where each node represents a single (possibly nested) column

Fields

root: NamesOnlySchemaNode

The root node of the schema

Implementations

impl NamesOnlySchema

pub fn new(root_nodes: Vec<NamesOnlySchemaNode>) -> Self

Create a new names-only schema

pub fn new_with_registry( root_nodes: Vec<NamesOnlySchemaNode>, registry: ExtensionsRegistry ) -> Self

Create a names-only schema with the given registry

Trait Implementations

impl Debug for NamesOnlySchema

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

Formats the value using the given formatter.

impl PartialEq for NamesOnlySchema

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

This method tests for self and other values to be equal, and is used by ==.

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

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