Struct Variable 

pub struct Variable<T> {
    pub value: Option<T>,
    pub tags: Vec<[String; 2]>,
}

Generic variable resource for storing any type of data with metadata.

用于存储任意类型数据及元数据的通用变量资源。

Fields

value: Option<T>

The stored value of the variable.

变量的存储值。

tags: Vec<[String; 2]>

Key-value pairs for categorization and metadata.

用于分类和元数据的键值对标签。

Implementations

impl<T> Variable<T>

pub fn value(self, value: Option<T>) -> Self

pub fn tags(self, tags: &[[String; 2]], replace: bool) -> Self

Trait Implementations

impl<T: Clone> Clone for Variable<T>

fn clone(&self) -> Variable<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Variable<T>

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

Formats the value using the given formatter.

impl<T> Default for Variable<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: PartialEq> PartialEq for Variable<T>

fn eq(&self, other: &Variable<T>) -> 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<T: PartialOrd> PartialOrd for Variable<T>

fn partial_cmp(&self, other: &Variable<T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<T: Debug + Send + Sync + 'static> RustConstructorResource for Variable<T>

fn as_any(&self) -> &dyn Any

Returns a reference to the resource as Any for extract the specific type.

fn as_any_mut(&mut self) -> &mut dyn Any

Returns a mutable reference to the resource as Any for extract the specific type.

fn display_display_info(&self) -> Option<DisplayInfo>

Retrieves the display info field for this resource.

fn modify_display_info(&mut self, _display_info: DisplayInfo)

Updates the display info field for this resource.

fn display_tags(&self) -> Vec<[String; 2]>

Returns all tags associated with this resource.

fn modify_tags(&mut self, tags: &[[String; 2]], replace: bool)

Updates the tags for this resource.
