Struct Signature

pub struct Signature { /* private fields */ }

A function signature.

Implementations

impl Signature

pub fn new( parameter_types: Vec<Option<SequenceType>>, return_type: Option<SequenceType>, ) -> Self

pub fn parameter_types(&self) -> &[Option<SequenceType>]

The parameter types of the function.

pub fn return_type(&self) -> Option<&SequenceType>

The return type of the function.

pub fn arity(&self) -> usize

Return the arity of the function signature.

pub fn display_representation(&self) -> String

Display representation

Trait Implementations

impl Clone for Signature

fn clone(&self) -> Signature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Signature

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

Formats the value using the given formatter.

impl From<Signature> for Signature

fn from(signature: Signature) -> Self

Converts to this type from the input type.

impl PartialEq for Signature

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