Fields

name: String

Type name

parameters: Vec<TypeParam>

Type parameters (e.g., for generic types)

structure: Option<ConcreteType>

variadic: Option<bool>

Whether this type can have variadic parameters

description: Option<String>

Implementations

impl CustomType

pub fn validate_name(name: &str) -> Result<(), InvalidTypeName>

Check if this type name is valid according to Substrait naming rules (see the Identifier rule in substrait/grammar/SubstraitLexer.g4). Identifiers are case-insensitive and must start with a an ASCII letter, _, or $, followed by ASCII letters, digits, _, or $.

pub fn new( name: String, parameters: Vec<TypeParam>, structure: Option<ConcreteType>, variadic: Option<bool>, description: Option<String>, ) -> Result<Self, ExtensionTypeError>

Create a new custom type with validation

Trait Implementations

impl Clone for CustomType

fn clone(&self) -> CustomType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CustomType

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

Formats the value using the given formatter.

impl From<CustomType> for SimpleExtensionsTypesItem

fn from(value: CustomType) -> Self

Converts to this type from the input type.

impl PartialEq for CustomType

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