Enum ProguardError 

#[non_exhaustive]
pub enum ProguardError {
    Io(Error),
    File {
        path: PathBuf,
        source: Error,
    },
    Syntax {
        line: usize,
        reason: &'static str,
    },
}

Why a mapping file could not be read at all.

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.

Io(Error)

Reading the mapping from a reader failed (or it is not UTF-8).

File

The mapping file could not be read (or is not UTF-8).

Fields

path: PathBuf

The file.

source: Error

The read error.

Syntax

A line that is not mapping syntax at all.

Fields

line: usize

1-based line in the mapping file.

reason: &'static str

What was expected.

Trait Implementations

impl Debug for ProguardError

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

Formats the value using the given formatter.

impl Display for ProguardError

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

Formats the value using the given formatter.

impl Error for ProguardError

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<Error> for ProguardError

fn from(source: Error) -> Self

Converts to this type from the input type.
