Enum LoadError 

pub enum LoadError {
    StdinNeedsFormat,
    MixedFormats,
    Directory {
        path: PathBuf,
    },
    UnknownExtension {
        path: PathBuf,
    },
}

Why a positional could not be turned into a layer.

Reports source selection failures without frontend flag vocabulary. Format mismatches have no single source path; other input failures do.

Variants

StdinNeedsFormat

- was given without an explicit input format.

MixedFormats

Inferred input formats differ.

Directory

A positional named a directory.

Fields

path: PathBuf

The directory that was named.

UnknownExtension

A positional’s extension is neither json nor toml.

Fields

path: PathBuf

The file whose extension said nothing.

Implementations

impl LoadError

pub fn path(&self) -> Option<&Path>

The path this failed on, or None for stdin and mixed formats.

Trait Implementations

impl Clone for LoadError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LoadError

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

Formats the value using the given formatter.

impl Display for LoadError

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

Formats the value using the given formatter.

impl Eq for LoadError

impl Error for LoadError

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 PartialEq for LoadError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
