Enum FolderError 

#[non_exhaustive]
pub enum FolderError {
    Read {
        path: PathBuf,
        error: Error,
    },
    TooBig {
        path: PathBuf,
        limit: u64,
    },
    NotUtf8 {
        path: PathBuf,
    },
    Layer(LayerError),
}

Why a folder could not be read into a layer (read_folder).

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

A file or folder that could not be read.

Fields

path: PathBuf

The file or folder.

error: Error

What the system said.

TooBig

A file over the limit.

Fields

path: PathBuf

The file.

limit: u64

The limit, in bytes.

NotUtf8

A file or folder whose name isn’t UTF-8, which no read can name.

Fields

path: PathBuf

The file or folder.

Layer(LayerError)

A path the layer refused (a backslash in a name, where the system allows one).

Trait Implementations

impl Debug for FolderError

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

Formats the value using the given formatter.

impl Display for FolderError

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

Formats the value using the given formatter.

impl Error for FolderError

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.
