Enum InstalledMetadataError 

#[non_exhaustive]
pub enum InstalledMetadataError {
    Read {
        path: PathBuf,
        source: ReadError,
    },
    View {
        path: PathBuf,
        source: ViewError,
    },
}

Errors reading a typed view from an installed-package metadata artifact.

The file layer and typed view layer remain separate: callers can inspect whether a failure came from bounded file reading or from validating the decoded metadata object. The artifact path is retained for both variants, including read failures that do not carry a path themselves (for example, a decompression or size-limit 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.

Read

Reading the canonical installed metadata artifact failed.

Fields

path: PathBuf

source: ReadError

View

The artifact was read, but its decoded object did not match the typed metadata view’s supported schema.

Fields

path: PathBuf

source: ViewError

Implementations

impl InstalledMetadataError

pub fn path(&self) -> &Path

Returns the canonical artifact path selected for the read.

Trait Implementations

impl Debug for InstalledMetadataError

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

Formats the value using the given formatter.

impl Display for InstalledMetadataError

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

Formats the value using the given formatter.

impl Error for InstalledMetadataError

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>)
