Enum Error

#[non_exhaustive]
pub enum Error {
    AlpmType(Error),
    Io(&'static str, Error),
    IoPath(PathBuf, &'static str, Error),
    InvalidUTF8(FromUtf8Error),
    NoInputFile,
    ParseError(String),
    SourceInfoErrors(SourceInfoErrors),
    Json(Error),
}

The high-level error that can occur when using this crate.

Notably, it contains two important enums in the context of parsing:

• ParseError is a already formatted error generated by the winnow parser. This effectively means that some invalid data has been encountered.
• SourceInfoErrors is a list of all logical or lint errors that’re encountered in the final step. This error also contains the original file on which the errors occurred.

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.

AlpmType(Error)

ALPM type error

Io(&'static str, Error)

IO error

IoPath(PathBuf, &'static str, Error)

IO error with additional path info for more context.

InvalidUTF8(FromUtf8Error)

UTF-8 parse error when reading the input file.

NoInputFile

No input file given.

This error only occurs when running the crate::commands functions.

ParseError(String)

A parsing error that occurred during winnow file parsing.

SourceInfoErrors(SourceInfoErrors)

A list of errors that occurred during the final SRCINFO data parsing step.

These may contain any combination of SourceInfoError.

Json(Error)

JSON error while creating JSON formatted output.

This error only occurs when running the crate::commands functions.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<FromUtf8Error> for Error

fn from(source: FromUtf8Error) -> Self

Converts to this type from the input type.
