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.

Protocol(ParseError)

Store(StoreError)

Engine(EngineError)

Io(Error)

Other(Error)

StaleToken

The agent’s pre-image token did not match the page’s current token.

Fields

current: StateToken

reason: &'static str

NoSession

No active session for this connection.

UnknownSession(String)

Session id refers to no known session.

UnknownPage(String)

Page id refers to no known page in this session.

UnknownRef(u32)

Ref does not exist in the page’s current tree.

BadRequest(String)

The wire request was malformed.

Unsupported

Engine’s capability set excludes this primitive on this platform.

Fields

engine: &'static str

primitive: &'static str

Implementations

impl DaemonError

pub fn wire(&self) -> (ErrorCode, Vec<String>)

The wire-format error code and args for this error.

Trait Implementations

impl Debug for DaemonError

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

Formats the value using the given formatter.

impl Display for DaemonError

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

Formats the value using the given formatter.

impl Error for DaemonError

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.
