Enum StoreError 

pub enum StoreError {
    Missing {
        type_name: &'static str,
    },
    ExpiredScope,
    BorrowConflict {
        type_name: &'static str,
    },
}

Failure to register or borrow a store through a NodeContext.

Variants

Missing

No provider of the requested type exists on this node or its logical ancestors.

Fields

type_name: &'static str

ExpiredScope

The context is not mounted, its mount has ended, or its provider ancestry has expired.

BorrowConflict

The selected provider is already borrowed by a with_store closure. Lookup does not fall through to an outer provider in this case.

Fields

type_name: &'static str

Trait Implementations

impl Clone for StoreError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StoreError

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

Formats the value using the given formatter.

impl Display for StoreError

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

Formats the value using the given formatter.

impl Eq for StoreError

impl Error for StoreError

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 PartialEq for StoreError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
