Struct FunctionType

pub struct FunctionType<'input> { /* private fields */ }

A function type.

Implementations

impl<'input> FunctionType<'input>

pub fn parameters(&self) -> &[ParameterType<'input>]

The parameters of the function.

pub fn return_type<'a>( &self, hash: &'a FileHash<'input>, ) -> Option<Cow<'a, Type<'input>>>

The return type of the function.

pub fn byte_size(&self) -> Option<u64>

The size in bytes of an instance of this type.

pub fn cmp_id( hash_a: &FileHash<'_>, a: &FunctionType<'_>, hash_b: &FileHash<'_>, b: &FunctionType<'_>, ) -> Ordering

Compare the identifying information of two types.

Function types are considered equal if they have the same parameter types and return types. Parameter names are ignored.

This can be used to sort, and to determine if two types refer to the same definition (even if there are differences in the definitions).

Trait Implementations

impl<'input> Clone for FunctionType<'input>

fn clone(&self) -> FunctionType<'input>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'input> Debug for FunctionType<'input>

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

Formats the value using the given formatter.

impl<'input> Default for FunctionType<'input>

fn default() -> FunctionType<'input>

Returns the “default value” for a type.
