Enum ReactiveError 

pub enum ReactiveError {
    Cycle,
    DependencyCycle,
    TypeMismatch,
}

Errors produced by the reactive runtime.

Variants

Cycle

A computation would read its own result — runtime self-reference cycle detected via the thread-local evaluation stack.

DependencyCycle

Inserting a dependency edge would introduce a cycle in the dep graph — detected via DFS before the edge is committed.

TypeMismatch

The stored value’s concrete type does not match the requested T.

Trait Implementations

impl Clone for ReactiveError

fn clone(&self) -> ReactiveError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReactiveError

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

Formats the value using the given formatter.

impl Display for ReactiveError

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

Formats the value using the given formatter.

impl Error for ReactiveError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for ReactiveError

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

Equality operator ==.

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

Inequality operator !=.
