Enum ConstantDatum 

pub enum ConstantDatum {
    Boolean(bool),
    Double(f64),
    Integer(i32),
    Text(String),
}

A typed scalar value, used both in the compile-time constant pool and as a return value when inspecting global variables after execution.

Only scalar types that can be hashed are included here. Arrays are never stored as ConstantDatum.

Variants

Boolean(bool)

A boolean value.

Double(f64)

A double-precision floating-point value.

Integer(i32)

A 32-bit signed integer value.

Text(String)

A string value.

Implementations

impl ConstantDatum

pub fn as_source(&self) -> String

Formats this value as EndBASIC source code.

Trait Implementations

impl Clone for ConstantDatum

fn clone(&self) -> ConstantDatum

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConstantDatum

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

Formats the value using the given formatter.

impl From<&str> for ConstantDatum

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<String> for ConstantDatum

fn from(value: String) -> Self

Converts to this type from the input type.

impl From<bool> for ConstantDatum

fn from(value: bool) -> Self

Converts to this type from the input type.

impl From<f64> for ConstantDatum

fn from(value: f64) -> Self

Converts to this type from the input type.

impl From<i32> for ConstantDatum

fn from(value: i32) -> Self

Converts to this type from the input type.

impl Hash for ConstantDatum

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 ConstantDatum

fn eq(&self, other: &Self) -> 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.
