Enum OptionValue 

pub enum OptionValue {
    Bool(bool),
    Integer(i64),
    String(String),
    Choice {
        value: String,
        choices: Vec<String>,
    },
}

Type-safe option value.

This is the core value type for editor options. Each variant maps to a common configuration pattern:

• Bool: Toggle settings (number, wrap, etc.)
• Integer: Numeric settings (tabwidth, scrolloff)
• String: Free-form text (theme name, paths)
• Choice: Enum-like selection from predefined values

Variants

Bool(bool)

Boolean on/off option (e.g., number, relativenumber)

Integer(i64)

Integer option (e.g., tabwidth, scrolloff)

String(String)

String option (e.g., theme, signcolumn)

Choice

Choice option with predefined valid values.

The choices field stores all valid values for validation.

Fields

value: String

Current selected value

choices: Vec<String>

All valid choices (for validation and completion)

Implementations

impl OptionValue

pub const fn bool(value: bool) -> Self

Create a boolean value.

pub const fn int(value: i64) -> Self

Create an integer value.

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

Create a string value.

pub fn choice(value: impl Into<String>, choices: Vec<String>) -> Self

Create a choice value.

Panics

Panics if choices is empty or if value is not in choices.

pub const fn as_bool(&self) -> Option<bool>

Try to get as boolean.

pub const fn as_int(&self) -> Option<i64>

Try to get as integer.

pub fn as_str(&self) -> Option<&str>

Try to get as string reference.

pub const fn type_name(&self) -> &'static str

Get the type name for error messages.

pub const fn same_type(&self, other: &Self) -> bool

Check if this value has the same type as another.

Trait Implementations

impl Clone for OptionValue

fn clone(&self) -> OptionValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptionValue

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

Formats the value using the given formatter.

impl Display for OptionValue

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

Formats the value using the given formatter.

impl PartialEq for OptionValue

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