Struct DuplicateItem

pub struct DuplicateItem<T, D = T> { /* private fields */ }

An item conflicts with existing items.

Implementations

impl<T, D> DuplicateItem<T, D>

pub fn new_item(&self) -> &T

Returns the new item that was attempted to be inserted.

pub fn duplicates(&self) -> &[D]

Returns the list of items that conflict with the new item.

pub fn into_parts(self) -> (T, Vec<D>)

Converts self into its constituent parts.

impl<T: Clone> DuplicateItem<T, &T>

pub fn into_owned(self) -> DuplicateItem<T>

Converts self to an owned DuplicateItem by cloning the list of duplicates.

If T is 'static, the owned form is suitable for conversion to Box<dyn std::error::Error>, anyhow::Error, and so on.

Trait Implementations

impl<T: Debug, D: Debug> Debug for DuplicateItem<T, D>

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

Formats the value using the given formatter.

impl<T: Debug, D: Debug> Display for DuplicateItem<T, D>

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

Formats the value using the given formatter.

impl<T: Debug, D: Debug> Error for DuplicateItem<T, D>

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.
