Enum Operand

pub enum Operand {
    String(String),
    Float(String),
    Number(i32),
}

Represents an operand, which can be one of several types.

Variants

String(String)

A string operand.

Float(String)

A floating-point operand (stored as a string).

Number(i32)

An integer operand.

Implementations

impl Operand

pub fn new_string(value: impl Into<String>) -> Self

Creates a new string operand.

Arguments

• value: The value of the string operand.

Returns

• A new Operand::String.

Examples

use gbf_core::operand::Operand;

let operand = Operand::new_string("Hello, world!");

pub fn new_float(value: impl Into<String>) -> Self

Creates a new float operand.

Arguments

• value: The value of the float operand.

Returns

• A new Operand::Float.

Examples

use gbf_core::operand::Operand;

let operand = Operand::new_float("3.14");

pub fn new_number(value: i32) -> Self

Creates a new number operand.

Arguments

• value: The value of the number operand.

Returns

• A new Operand::Number.

Examples

use gbf_core::operand::Operand;

let operand = Operand::new_number(42);

pub fn get_string_value(&self) -> Result<&str, OperandError>

Retrieves the value of the operand as a string reference, if applicable.

Returns

• The value of the operand as a string reference.

Errors

• OperandError::InvalidConversion if the operand is a number.

Examples

use gbf_core::operand::Operand;

let operand = Operand::new_string("Hello, world!");
let value = operand.get_string_value().unwrap();
assert_eq!(value, "Hello, world!");

pub fn get_number_value(&self) -> Result<i32, OperandError>

Retrieves the value of the operand as a number, if applicable.

Returns

• The value of the operand as a number.

Errors

• OperandError::InvalidConversion if the operand is a string.

Examples

use gbf_core::operand::Operand;

let operand = Operand::new_number(42);
let value = operand.get_number_value().unwrap();
assert_eq!(value, 42);

Trait Implementations

impl Clone for Operand

fn clone(&self) -> Operand

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Operand

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Operand

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Operand

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

Formats the value using the given formatter.

impl Hash for Operand

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 Operand

fn eq(&self, other: &Operand) -> 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 Serialize for Operand

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Operand

impl StructuralPartialEq for Operand
