Enum UpdateError 

#[non_exhaustive]
pub enum UpdateError {
    Fetch(String),
    NoArtifact(String),
    Checksum,
    Io {
        context: String,
        source: Error,
    },
}

Failure of a self-update.

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.

Fetch(String)

The manifest or binary could not be fetched.

NoArtifact(String)

No artifact for this platform.

Checksum

The download does not match the manifest.

Io

Replacing the binary failed.

Fields

context: String

What was being done.

source: Error

Cause.

Trait Implementations

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>)
