Enum TargetStateCaptureError 

pub enum TargetStateCaptureError {
    Empty,
    DuplicateRequest(usize),
    Unrequested(usize),
    DuplicateCapture(usize),
    Missing(usize),
}

Invalid target-state capture lifecycle.

Variants

Empty

At least one state tap must be requested.

DuplicateRequest(usize)

One layer was requested more than once.

Unrequested(usize)

A block emitted a state that was not requested.

DuplicateCapture(usize)

A requested state was captured more than once.

Missing(usize)

A requested block never emitted its output.

Trait Implementations

impl Eq for TargetStateCaptureError

impl Error for TargetStateCaptureError

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.
