Struct substrait_expr::builder::schema::TypeBuilder

pub struct TypeBuilder<'a> { /* private fields */ }

A builder object for creating user defined types

Implementations

impl<'a> TypeBuilder<'a>

pub fn unknown(&self) -> Type

Create an instance of the “unknown” type

This is a special type when it comes to function resolution. It will always match an argument, regardless of what type is expected. However, if it is present, then the function’s return type changes to unknown as
well.

This type is normally used when the schema is unknown or not type aware.

pub fn user_defined( &self, uri: impl Into<String>, name: impl AsRef<str> ) -> UserDefinedTypeBuilder

Create a builder that can create instances of a user defined type
