Enum PackageError 

pub enum PackageError {
    FileMissing(PathBuf),
    PackageNameInvalid(String),
    PackageNotFound(PackageName),
    Parse(Error, Option<PathBuf>),
    Recursion(VecDeque<PackageName>),
    TargetInvalid,
}

Errors that occur while opening or parsing Packages.

These errors are unrecoverable but useful for reporting.

Variants

FileMissing(PathBuf)

PackageNameInvalid(String)

PackageNotFound(PackageName)

Parse(Error, Option<PathBuf>)

Recursion(VecDeque<PackageName>)

TargetInvalid

Implementations

impl PackageError

pub fn append_recursion(&mut self, name: &PackageName)

Append PackageName if the error is a recursion error.

The PackageError::Recursion variant is a stack of package names that caused the recursion limit to be reached. This functions conditionally pushes a package name if the error is a recursion error to make it easier to build the stack.

Trait Implementations

impl Debug for PackageError

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

Formats the value using the given formatter.

impl Display for PackageError

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

Formats the value using the given formatter.

impl Error for PackageError

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 From<PackageError> for Error

fn from(source: PackageError) -> Self

Converts to this type from the input type.
