Enum liberty_parse::ast::Value

pub enum Value {
    Bool(bool),
    Float(f64),
    FloatGroup(Vec<f64>),
    String(String),
    Expression(String),
}

Liberty value type

A wide range of types are defined for the Liberty syntax. Because there is little to no way to parse enumerated types from the syntax alone, enumerated types are parsed as the Value::Expression variant.

Variants

Bool(bool)

Boolean value, parsed from the keywords true and false

Float(f64)

Floating point value.

All numbers are parsed into f64. While the Liberty specification differentiates between integers and floating point values on a per-field basis, all are parsed into an f64.

FloatGroup(Vec<f64>)

Group of floating point values in quotation marks

For example, this complex attribute

values ( \
  "1.0, 2.0, 3.0", \
  "4.0, 5.0, 6.0" \
);

will be parsed into a Vec<Value::FloatGroup>.

String(String)

String enclosed in quotation marks

Expression(String)

Expression

Enumerated values, such as the delay_model simple attribute, are parsed as a Value::Expression.

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq<Value> for Value

fn eq(&self, other: &Value) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Value) -> bool

This method tests for !=.
