Enum SetError 

pub enum SetError {
    ValidationFailed(String),
    ApplyFailed(Vec<ApplyFailure>),
    FinalViolation {
        scope: String,
    },
}

Error outcomes returned by Control::set. A write can reject at validation (before fan-out), at apply (during fan-out), or up front because the control is final at its declaring scope. In every case the committed value is unchanged.

Variants

ValidationFailed(String)

The pre-fanout validator rejected the value. No applier was called. Message explains why.

ApplyFailed(Vec<ApplyFailure>)

One or more appliers returned Err (or timed out). The list carries the index + error message for each failure.

FinalViolation

The control was declared final at scope and is pinned to its Launch value. Runtime writes (any origin other than Launch) are rejected.

Fields

scope: String

Trait Implementations

impl Clone for SetError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SetError

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

Formats the value using the given formatter.

impl Display for SetError

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

Formats the value using the given formatter.

impl Eq for SetError

impl Error for SetError

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 SetError

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

Equality operator ==.

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

Inequality operator !=.
