Error type returned by library functions in this crate.

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.

CargoMetadata(String)

Cargo metadata failed to produce a dep graph.

InvalidWidgetMetadata

A widget crate declared an incomplete or invalid [package.metadata.plushie.widget] table.

Fields

crate_name: String

Cargo package whose manifest was malformed.

reason: String

Human-readable description of what was missing or wrong.

DuplicateTypeName

Two widgets declared the same type_name.

Fields

type_name: String

The colliding wire-protocol type name.

crates: String

Comma-separated list of crate names in collision.

BuiltinCollision

A widget declared a type name that is already registered by the built-in iced widget set.

Fields

crate_name: String

Cargo package responsible for the collision.

type_name: String

Wire-protocol type name that conflicts with a built-in.

DuplicateCrateBasename

Two widgets produced the same crate basename.

Fields

basename: String

The crate basename that collided.

crates: String

Comma-separated list of crate names / paths in collision.

InvalidConstructor

A widget’s constructor expression does not look like a valid Rust path + optional parenthesized call.

Fields

crate_name: String

Widget crate name.

constructor: String

Constructor expression that failed validation.

Io(Error)

Generic I/O failure during build or download.

CargoBuildFailed(ExitStatus)

Inner cargo build invocation exited with a non-zero status.

DownloadWithNativeWidgets

A cargo plushie download call found native widgets in the dep graph; the stock binary cannot register them.

Fields

widgets: String

Comma-separated list of native widget crate names.

Other(Error)

Any other error surfaced through anyhow.

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.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
