Enum ListError 

pub enum ListError {
    InvalidLimit,
    LimitTooLarge,
    InvalidCursor,
    CorruptRow,
    Storage(StorageError),
}

Failure modes of scan_page. ListError::code is the stable wire string.

Variants

InvalidLimit

limit == 0.

LimitTooLarge

limit > MAX_PAGE.

InvalidCursor

The supplied cursor is not a valid ULID token.

CorruptRow

A value on the page failed to deserialize into T.

Storage(StorageError)

A backend / mid-stream scan error, propagated.

Implementations

impl ListError

pub fn code(&self) -> &'static str

Stable, machine-readable code — the wire string the HTTP layer surfaces.

Trait Implementations

impl Debug for ListError

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

Formats the value using the given formatter.

impl Display for ListError

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

Formats the value using the given formatter.

impl Error for ListError

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<StorageError> for ListError

fn from(source: StorageError) -> ListError

Converts to this type from the input type.
