Why an install did not happen.

Variants

NotInCatalogue

The catalogue has no entry, so there is no pinned source to trust.

Fields

language: String

UntrustedSource

The URL is not one this build is willing to fetch from.

Fields

url: String

detail: String

Transport

The transfer failed.

Fields

url: String

detail: String

ContentMismatch

The bytes are not the bytes that were pinned.

Either the published dictionary changed or something served different content. Those are indistinguishable from here, so both stop.

Fields

url: String

expected: String

actual: String

NoRoom

The destination cannot hold it.

Fields

path: PathBuf

needed: u64

available: u64

Destination

The destination cannot be written.

Fields

path: PathBuf

detail: String

Unusable(PackError)

It arrived intact and is not a usable dictionary.

Trait Implementations

impl Error for InstallError

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:

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>)
