Domain-specific errors

All domain errors are value types with no external dependencies. Uses thiserror for ergonomic error handling.

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.

InvalidStateTransition(String)

Invalid state transition attempted

InvalidStreamState(String)

Invalid stream state

InvalidSessionState(String)

Invalid session state

InvalidFrame(String)

Invalid frame structure or content

InvariantViolation(String)

Stream invariant violation

InvalidPriority(String)

Invalid priority value (must be 1-255)

InvalidPath(String)

Invalid JSON path format

SessionNotFound(String)

Session not found

StreamNotFound(String)

Stream not found

TooManyStreams(String)

Too many concurrent streams

Logic(String)

General domain logic error

Io(String)

I/O operation failed

NotFound(String)

Resource not found

ConcurrencyConflict(String)

Concurrency conflict detected

CompressionError(String)

Compression operation failed

ValidationError(String)

Validation failed

InvalidInput(String)

Invalid input provided

InternalError(String)

Internal error (should not happen)

SecurityViolation(String)

Security policy violation

ResourceExhausted(String)

Resource exhausted (memory, connections, etc.)

Implementations

impl DomainError

pub fn invariant_violation(message: impl Into<String>) -> DomainError

Create an invariant violation error

pub fn invalid_transition(from: &str, to: &str) -> DomainError

Create an invalid state transition error

Trait Implementations

impl Debug for DomainError

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

Formats the value using the given formatter.

impl Display for DomainError

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

Formats the value using the given formatter.

impl Error for DomainError

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<DomainError> for ApplicationError

fn from(source: DomainError) -> Self

Converts to this type from the input type.

impl From<DomainError> for SchemaValidationError

fn from(error: DomainError) -> SchemaValidationError

Converts to this type from the input type.

impl From<String> for DomainError

fn from(error: String) -> DomainError

Converts to this type from the input type.
