Enum HashError 

pub enum HashError {
    InvalidPath(RelativePathError),
    AbsoluteNotUnderRoot(String),
    AmbiguousPath {
        path: String,
        nfc: String,
    },
    Io {
        path: PathBuf,
        source: Error,
    },
    Walk(ModuleWalkError),
    Tree(TreeError),
}

An error during content hashing.

Variants

InvalidPath(RelativePathError)

A path supplied to Hasher::try_add failed relative-path validation.

AbsoluteNotUnderRoot(String)

An absolute path was supplied that does not live under the module root.

AmbiguousPath

A new path collides under Unicode Normalization Form C (NFC) with a path that was already recorded. The spec requires the module’s set of relative paths to be unique under NFC.

Fields

path: String

The newly-submitted path that collided.

nfc: String

The shared NFC form.

Io

I/O failure while reading a file.

Fields

path: PathBuf

The path of the file that failed to read.

source: Error

The underlying I/O error.

Walk(ModuleWalkError)

A tree walk error (symlink containment, metadata target, etc.).

Tree(TreeError)

A module file-tree validation error (reserved-filename placement, NFC duplicate paths).

Trait Implementations

impl Debug for HashError

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

Formats the value using the given formatter.

impl Display for HashError

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

Formats the value using the given formatter.

impl Error for HashError

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.
