Enum BatchLabelError 

#[non_exhaustive]
pub enum BatchLabelError {
    Empty {
        index: usize,
    },
    Duplicate {
        label: String,
        first_index: usize,
        duplicate_index: usize,
    },
}

Invalid labels, rejected before the operation performs work.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Empty

An input label was empty.

Fields

index: usize

Zero-based position of the empty label.

Duplicate

Two inputs used the same label.

Fields

label: String

Repeated label.

first_index: usize

Position of the first occurrence.

duplicate_index: usize

Position of the repeated occurrence.

impl Eq for BatchLabelError

impl Error for BatchLabelError

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.
