Enum SpillError 

pub enum SpillError {
    Io(Error),
    BatchTooLarge {
        size: usize,
        limit: usize,
    },
    Codec(String),
}

Errors raised by the spill helper.

Variants

Io(Error)

impl Error for SpillError

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 From<Error> for SpillError

fn from(e: Error) -> Self

Converts to this type from the input type.
