Enum PackageError 

#[non_exhaustive]
pub enum PackageError {
    Usage(String),
    Fetch(String),
    Invalid(String),
    Declined(String),
    Io {
        context: String,
        source: Error,
    },
}

Failure of a package command (printed as Error: …).

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.

Usage(String)

Bad command line.

Fetch(String)

The source could not be fetched or unpacked.

Invalid(String)

The package is invalid.

Declined(String)

The user declined, or --yes is missing without a terminal.

Io

File system failure.

Fields

context: String

What was being done.

source: Error

Cause.

Trait Implementations

impl Debug for PackageError

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

Formats the value using the given formatter.

impl Display for PackageError

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

Formats the value using the given formatter.

impl Error for PackageError

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.
