Enum Function

pub enum Function {
    Monomorphic(MonomorphicFunction),
    Polymorphic(PolymorphicFunction),
}

Represents a WDL function.

Variants

Monomorphic(MonomorphicFunction)

The function is monomorphic.

Polymorphic(PolymorphicFunction)

The function is polymorphic.

Implementations

impl Function

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

Binds the function to the given arguments.

pub fn realize_unconstrained_return_type(&self, arguments: &[Type]) -> Type

Realizes the return type of the function without constraints.

This is typically called after a failure to bind a function so that the return type can be calculated despite the failure.

As such, it attempts to realize any type parameters without constraints, as an unsatisfied constraint likely caused the bind failure.

Trait Implementations

impl Debug for Function

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

Formats the value using the given formatter.

impl From<MonomorphicFunction> for Function

fn from(value: MonomorphicFunction) -> Self

Converts to this type from the input type.

impl From<PolymorphicFunction> for Function

fn from(value: PolymorphicFunction) -> Self

Converts to this type from the input type.
