Enum MsvcError 

pub enum MsvcError {
    Json {
        at: usize,
        wanted: &'static str,
    },
    NoManifest,
    NoLicence,
    NothingFound(&'static str),
    NoPackage(String),
    NoInstaller(String),
    OutOfOrder(String),
}

Why a manifest could not be read or could not be chosen from.

Variants

Json

The document did not parse.

The reader behind this is not part of the interface, so what comes out of it is the two things a person needs rather than the reader’s own type: what was expected and where.

Fields

at: usize

The byte offset in the document.

wanted: &'static str

What was expected there, in the words a person would use.

NoManifest

The channel manifest has no installer manifest in it, which means it is not one.

NoLicence

The channel manifest names no licence, and a download that cannot show one is a download that does not happen.

NothingFound(&'static str)

The installer manifest has none of something there has to be one of.

NoPackage(String)

A package the selection needs is not in the manifest.

NoInstaller(String)

A Windows SDK installer the selection needs is not among the SDK package’s files.

OutOfOrder(String)

A package wrote its payloads before its id, which is a manifest laid out in a way this reader was written not to guess at.

Trait Implementations

impl Clone for MsvcError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MsvcError

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

Formats the value using the given formatter.

impl Display for MsvcError

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

Formats the value using the given formatter.

impl Eq for MsvcError

impl Error for MsvcError

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 PartialEq for MsvcError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
