Enum cacache::Error

pub enum Error {
    EntryNotFound(PathBuf, String),
    SizeMismatch(usize, usize),
    IoError(Error, String),
    SerdeError(Error, String),
    IntegrityError(Error),
}

Error type returned by all API calls.

Variants

EntryNotFound(PathBuf, String)

Returned when an index entry could not be found during lookup.

SizeMismatch(usize, usize)

Returned when a size check has failed.

IoError(Error, String)

Returned when a general IO error has occurred.

SerdeError(Error, String)

Returned when a general serde error has occurred.

IntegrityError(Error)

Returned when an integrity check has failed.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Diagnostic for Error

fn code(&self) -> Option<Box<dyn Display + '_>>

Unique diagnostic code that can be used to look up more information about this Diagnostic. Ideally also globally unique, and documented in the toplevel crate’s documentation for easy searching. Rust path format (foo::bar::baz) is recommended, but more classic codes like E0123 or enums will work just fine.

fn url(&self) -> Option<Box<dyn Display + '_>>

URL to visit for a more detailed explanation/help about this Diagnostic.

fn severity(&self) -> Option<Severity>

Diagnostic severity. This may be used by ReportHandlers to change the display format of this diagnostic.

fn help<'a>(&'a self) -> Option<Box<dyn Display + 'a, Global>>

Additional help text related to this Diagnostic. Do you have any advice for the poor soul who’s just run into this issue?

fn source_code(&self) -> Option<&dyn SourceCode>

Source code to apply this Diagnostic’s Diagnostic::labels to.

fn labels(&self) -> Option<Box<dyn Iterator<Item = LabeledSpan>, Global>>

Labels to apply to this Diagnostic’s Diagnostic::source_code

fn related<'a>(
    &'a self
) -> Option<Box<dyn Iterator<Item = &'a (dyn Diagnostic + 'a)> + 'a, Global>>

Additional related Diagnostics.

fn diagnostic_source(&self) -> Option<&dyn Diagnostic>

The cause of the error.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

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, 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 From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
