Enum ConcurrencyError 

pub enum ConcurrencyError {
    NotMostRecent,
    CasFailed,
}

PutQuery for crate::MutableItem errors

Variants

NotMostRecent

The crate::MutableItem::seq is less than or equal the sequence from another signed item.

Try reading most recent mutable item before writing again.

CasFailed

The CAS condition does not match the seq of the most recent known signed item.

Trait Implementations

impl Clone for ConcurrencyError

fn clone(&self) -> ConcurrencyError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConcurrencyError

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

Formats the value using the given formatter.

impl Display for ConcurrencyError

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

Formats the value using the given formatter.

impl Error for ConcurrencyError

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<ConcurrencyError> for AnyError

fn from(value: ConcurrencyError) -> AnyError

Converts to this type from the input type.

impl From<ConcurrencyError> for PutError

fn from(source: ConcurrencyError) -> Self

Converts to this type from the input type.

impl From<ConcurrencyError> for PutMutableError

fn from(source: ConcurrencyError) -> Self

impl StackError for ConcurrencyError

fn as_std(&self) -> &(dyn Error + Send + Sync + 'static)

Returns this error as a std error reference.

fn into_std(self: Box<Self>) -> Box<dyn Error + Send + Sync>

Returns this error as a std error.

fn as_dyn(&self) -> &dyn StackError

Returns this error as a dyn StackError.

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