Struct Registry 

pub struct Registry { /* private fields */ }

Available on crate feature parse only.

Extension Registry that manages Substrait extensions

This registry is immutable and reusable across multiple plans. It provides URN + name based lookup for extension types. Function parsing will be added in a future update.

Implementations

impl Registry

pub fn new<I: IntoIterator<Item = ExtensionFile>>( extensions: I, ) -> Result<Self, SimpleExtensionsError>

Create a new Global Registry from validated extension files.

Any duplicate URNs will raise an error.

pub fn extensions(&self) -> impl Iterator<Item = (&Urn, &SimpleExtensions)>

Get an iterator over all extension files in this registry

pub fn from_core_extensions() -> Self

Available on crate feature extensions only.

Create a Global Registry from the built-in core extensions.

Most core extensions are included. Some are skipped due to bugs in the upstream YAML files (see https://github.com/substrait-io/substrait/issues/935).

pub fn get_type(&self, urn: &Urn, name: &str) -> Option<&CustomType>

Get a type by URN and name

pub fn get_scalar_function( &self, urn: &Urn, name: &str, ) -> Option<&ScalarFunction>

Get a scalar function by URN and name.

TODO: Add support for retrieving functions by their full signature shorthand (e.g., “add:i32_i32”).

Trait Implementations

impl Debug for Registry

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

Formats the value using the given formatter.
