Errors in message store operations.

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.

StoreFailed

Failed to store message.

Fields

seq_num: u64

Sequence number of the message.

reason: String

Reason for failure.

RetrieveFailed

Failed to retrieve message.

Fields

seq_num: u64

Sequence number of the message.

reason: String

Reason for failure.

NotFound

Message not found in store.

Fields

seq_num: u64

Sequence number of the missing message.

RangeNotAvailable

No message is available anywhere in the requested range.

The bounds are inclusive, which is how a FIX ResendRequest expresses them. A half-open Range<u64> cannot represent an upper bound of u64::MAX — the “to infinity” case a ResendRequest with EndSeqNo (16) = 0 asks for — without an end + 1 that overflows, so the bounds are carried as two numbers and no arithmetic is performed on them.

Fields

begin: u64

First requested sequence number, inclusive.

end: u64

Last requested sequence number, inclusive.

InvalidRange

The requested range is inverted: begin is above end.

This is a caller error, not an empty result. It is reported rather than normalised because a store cannot tell an inverted range apart from a range that happens to hold nothing, and silently answering “empty” hides the bug that produced it.

Fields

begin: u64

First requested sequence number, inclusive.

end: u64

Last requested sequence number, inclusive.

Corrupted

Store is corrupted.

Fields

reason: String

Description of the corruption.

Io(String)

I/O error in persistent store.

Trait Implementations

impl Clone for StoreError

fn clone(&self) -> StoreError

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, __formatter: &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 From<StoreError> for FixError

fn from(source: StoreError) -> Self

Converts to this type from the input type.

impl PartialEq for StoreError

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for StoreError
