Struct Function

pub struct Function {
    pub parameters: Vec<String>,
    pub externals: Vec<String>,
    pub register_count: usize,
    pub rolling_record_count: usize,
    pub instructions: Vec<Instruction>,
}

A function in the intermediate representation. This is the output of a compiler.

Fields

parameters: Vec<String>

The parameters that the function takes.

externals: Vec<String>

The external variables that the function uses.

register_count: usize

The number of registers the function uses.

rolling_record_count: usize

The number of rolling records the function uses.

instructions: Vec<Instruction>

The instructions that make up the function.

Implementations

impl Function

pub fn arity(&self) -> usize

Answer the arity of the function.

Returns

The number of parameters that the function requires.

Trait Implementations

impl Clone for Function

fn clone(&self) -> Function

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Function

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Function

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Function

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

Formats the value using the given formatter.

impl Hash for Function

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 Function

fn eq(&self, other: &Function) -> 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 Serialize for Function

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Function

impl StructuralPartialEq for Function
