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.

GitHub(Error)

GitHub API or connector error.

Io(Error)

Filesystem or process I/O error.

Semver(Error)

Semantic-version parsing error.

Reqwest(Error)

HTTP request or response-body error.

Minisign(Error)

Minisign decode or verification error.

Http(Error)

Generic HTTP protocol or header construction error.

InvalidHeaderValue(InvalidHeaderValue)

Invalid HTTP header value.

InvalidHeaderName(InvalidHeaderName)

Invalid HTTP header name.

UnsupportedArch

The current CPU architecture is not supported.

UnsupportedOs

The current operating system is not supported.

AssetNotFound

No suitable artifact could be found for the requested target.

FailedToDetermineExtractPath

The install target path could not be derived from the executable path.

InsecureTransportProtocol

An update endpoint used an insecure transport protocol.

TargetNotFound(String)

The requested platform key was not present in the remote release metadata.

MissingSignatureAsset(String)

A matching detached signature asset was not found for the selected artifact.

Network(String)

Generic network or transport failure represented as a message.

InvalidUpdaterFormat

Downloaded installer or archive bytes did not match the expected format.

TempDirNotFound

Temporary staging directory creation failed.

InsufficientPrivileges

Windows elevation or installer execution was denied.

FileInUse

Windows installer could not proceed because files are in use.

InstallerExecutionFailed(i32)

Windows installer launch returned an execution error code.

UserCancelledElevation

Windows elevation prompt was cancelled by the user.

Json(Error)

JSON parsing or serialization error.

Time(Parse)

RFC3339 or other time parsing error.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
