Enum Error 

#[non_exhaustive]
pub enum Error {
    AlpmTypes(Error),
    Io(&'static str, Error),
    IoPathError {
        path: PathBuf,
        context: &'static str,

    ParseError(String),
    MissingSection(SectionKeyword),

    InvalidFormat,
}

The error that can occur when working with the ALPM database desc files.

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.

AlpmTypes(Error)

An alpm_types::Error.

Io(&'static str, Error)

IO error.

IoPathError

An I/O error occurred at a path.

Fields

path: PathBuf

The path at which the error occurred.

context: &'static str

The context in which the error occurred.

This is meant to complete the sentence “I/O error at path while “.

source: Error

The source error.

IoReadError

I/O error while reading a buffer.

Fields

context: &'static str

The context in which the error occurred.

This is meant to complete the sentence “Read error while “.

source: Error

The error source.

ParseError(String)

A winnow parser for a type didn’t work and produced an error.

MissingSection(SectionKeyword)

A section is missing in the parsed data.

DuplicateSection(SectionKeyword)

A section is duplicated in the parsed data.

NoInputFile

No input file given.

UnsupportedSchemaVersion(String)

Unsupported schema version.

InvalidFormat

Failed to parse v1 or v2.

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<'a> From<ParseError<&'a str, ContextError>> for Error

fn from(value: ParseError<&'a str, ContextError>) -> Self

Converts a [winnow::error::ParseError] into an Error::ParseError.
