Struct ExternSignature

pub struct ExternSignature { /* private fields */ }

An extern signature with a return type and parameters.

Implementations

impl ExternSignature

pub fn new( return_type: Option<ScalarType>, parameters: Vec<ExternParameter>, ) -> Self

Create a new extern signature.

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

pub fn parameters(&self) -> &[ExternParameter]

Trait Implementations

impl Clone for ExternSignature

fn clone(&self) -> ExternSignature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExternSignature

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

Formats the value using the given formatter.

impl FromStr for ExternSignature

type Err = ExternError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for ExternSignature

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ExternSignature

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

impl Quil for ExternSignature

fn write( &self, writer: &mut impl Write, fall_back_to_debug: bool, ) -> Result<(), ToQuilError>

Write the Quil representation of the item to the given writer. If fall_back_to_debug is true, then it must not return an error.

fn to_quil(&self) -> Result<String, ToQuilError>

Return a string in valid Quil syntax or an error if the item cannot be represented with valid Quil.

fn to_quil_or_debug(&self) -> String

Return a string in valid Quil syntax if possible. Any individual component of this object which cannot be represented in Quil will be replaced with a Debug representation of that component.

impl TryFrom<Pragma> for ExternSignature

type Error = ExternError

The type returned in the event of a conversion error.

fn try_from(value: Pragma) -> Result<Self, ExternError>

Performs the conversion.
