Struct Constant 

pub struct Constant {
    pub type_name: String,
    pub name: String,
    pub value: PrimitiveValue,
    pub annotations: Annotations,
}

Constant definition

Fields

type_name: String

Primitive type of the constant

name: String

Name of the constant

value: PrimitiveValue

Value of the constant

annotations: Annotations

Annotations attached to this constant

Implementations

impl Constant

pub fn new( primitive_type: &str, name: &str, value_string: &str, ) -> ParseResult<Self>

Create a new constant

Errors

Returns an error if:

• The primitive type is not a valid ROS2 primitive type
• The constant name doesn’t follow valid naming conventions
• The value string cannot be parsed for the given primitive type

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 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.
