Struct PolymorphicFunction

pub struct PolymorphicFunction { /* private fields */ }

Represents a polymorphic function.

In this context, a polymorphic function has more than one type (i.e. signature); overload resolution is used to determine which signature binds to the function call.

Implementations

impl PolymorphicFunction

pub fn new(signatures: Vec<FunctionSignature>) -> Self

Constructs a new polymorphic function.

Panics

Panics if the number of signatures is less than two.

pub fn minimum_version(&self) -> SupportedVersion

Gets the minimum WDL version required to call this function.

pub fn param_min_max(&self, version: SupportedVersion) -> Option<(usize, usize)>

Gets the minimum and maximum number of parameters the function has for the given WDL version.

Returns None if the function is not supported for the given version.

pub fn signatures(&self) -> &[FunctionSignature]

Gets the signatures of the function.

pub fn bind<'a>( &'a self, version: SupportedVersion, arguments: &[Type], ) -> Result<Binding<'a>, FunctionBindError>

Binds the function to the given arguments.

This performs overload resolution for the polymorphic function.

Trait Implementations

impl Debug for PolymorphicFunction

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

Formats the value using the given formatter.

impl From<PolymorphicFunction> for Function

fn from(value: PolymorphicFunction) -> Self

Converts to this type from the input type.
