Enum Error

pub enum Error {
    UnsupportedCapacity {
        capacity: usize,
    },
    Full,
    Ahead,
}

Enumeration of non-retryable errors that may happen while using flows.

Variants

UnsupportedCapacity

Flow buffers must be a power of two (e.g., 2, 4, 256, 2048…).

Fields

capacity: usize

Full

Publishing is temporarily impossible: the flow is full of unreceived data.

Ahead

The flow may or may not contain data, but the subscriber has already read all data presently in the flow.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

where Self: Debug + Display,

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

impl ErrorCompat for Error

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.
