Enum Sig 

pub enum Sig {
    Var,
    Fun(Vec<String>),
    BuiltinFun(Vec<BuiltinFunArg>),
}

A signature structure.

The signature specifies whether a variable is a normal variable, a function, or a built-in function. If the variable is the function or the built-in funciton, the signature also specifies which arguments are passed to the function or the built-in function.

Variants

Var

A normal variable.

Fun(Vec<String>)

A function.

BuiltinFun(Vec<BuiltinFunArg>)

A built-in function.

Trait Implementations

impl Clone for Sig

fn clone(&self) -> Sig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Sig

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

Formats the value using the given formatter.

impl Eq for Sig

impl Hash for Sig

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 Ord for Sig

fn cmp(&self, other: &Sig) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Sig

fn eq(&self, other: &Sig) -> 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 PartialOrd for Sig

fn partial_cmp(&self, other: &Sig) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
