Struct Constant

pub struct Constant {
    pub name: Ident,
    pub ty: Option<Type>,
    pub literal: Literal,
    pub id: NodeId,
    pub span: Span,
}

An Ast node representing the declaration of a constant.

Fields

name: Ident

The name of the constant stream

ty: Option<Type>

The value type of the constant stream

literal: Literal

The literal defining the constant

id: NodeId

The id of the node in the Ast

span: Span

The span in the specification declaring the constant stream

Trait Implementations

impl Clone for Constant

fn clone(&self) -> Constant

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Constant

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

Formats the value using the given formatter.

impl Display for Constant

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

Formats the value using the given formatter.

impl Ord for Constant

fn cmp(&self, other: &Constant) -> 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 Constant

fn eq(&self, other: &Constant) -> 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 Constant

fn partial_cmp(&self, other: &Constant) -> 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.
