Enum probe_rs::debug::variable::VariableValue

pub enum VariableValue {
    Valid(String),
    Error(String),
    Empty,
}

A Variable will have either a valid value, or some reason why a value could not be constructed.

• If we encounter expected errors, they will be displayed to the user as defined below.
• If we encounter unexpected errors, they will be treated as proper errors and will propogated to the calling process as an Err()

Variants

Valid(String)

A valid value of this variable

Error(String)

Notify the user that we encountered a problem correctly resolving the variable.

• The variable will be visible to the user, as will the other field of the variable.
• The contained warning message will be displayed to the user.
• The debugger will not attempt to resolve additional fields or children of this variable.

Empty

The value has not been set. This could be because …

• It is too early in the process to have discovered its value, or …
• The variable cannot have a stored value, e.g. a struct. In this case, please use Variable::get_value to infer a human readable value from the value of the struct’s fields.

Implementations

impl VariableValue

pub fn is_valid(&self) -> bool

A VariableValue is valid if it doesn’t contain an Info or a Warning.

pub fn is_empty(&self) -> bool

No value or error is present

Trait Implementations

impl Clone for VariableValue

fn clone(&self) -> VariableValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VariableValue

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

Formats the value using the given formatter.

impl Default for VariableValue

fn default() -> Self

Returns the “default value” for a type.

impl Display for VariableValue

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

Formats the value using the given formatter.

impl PartialEq<VariableValue> for VariableValue

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
