Error interacting with the Nix store

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.

InitialEnumeration

Fields

source: Error

Underlying IO error

configuration: NixConfiguration

The configuration in use

Failure initially enumerating the nix store

Enumeration

Fields

source: Error

Underlying IO error

configuration: NixConfiguration

The configuration in use

Mid-enumeration failure

StripPrefix

Fields

source: StripPrefixError

Underlying error

Error stripping prefix, this is indicative of a configuration error

Regex

Fields

source: Error

Underlying error

Error building a regex, this really shouldn’t happen

PathParsing

Error parsing a nix store path

CacheError

Fields

e: Error

Underlying error

Error checking the cache

DifferentPrefixes

Tried to compare stores with different prefixes

Trait Implementations

impl Debug for StoreError

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

Formats the value using the given formatter.

impl Display for StoreError

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

Formats the value using the given formatter.

impl Error for StoreErrorwhere
    Self: Debug + Display,

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 source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn provide(&'a self, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl ErrorCompat for StoreError

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_>where
    Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.
