Enum version_number::parsers::original::ErrorReason

pub enum ErrorReason {
    ExpectedEndOfInput {
        extra_input: Vec<u8>,
    },
    ExpectedSeparator {
        got: Option<u8>,
    },
    ExpectedNumericToken {
        got: Option<u8>,
    },
    NumberError(NumberError),
}

Reasons for why a given input cannot be parsed to a Version.

Variants

ExpectedEndOfInput

When this error variant is returned, the parser expected that no more tokens should be present, but instead 1 or more additional tokens were not parsed yet. The extra_input field contains the remaining tokens.

The error display implementation tries to print these remaining tokens as a String.

Fields

extra_input: Vec<u8>

A Vec of unexpected tokens, which were still present while the parser expected to have reached the end-of-input for the given input.

ExpectedSeparator

When this error variant is returned, the ‘.’ token was expected, but a different token was present, or the end-of-input reached.

The got field shows the token read.

Fields

got: Option<u8>

Token read, or None if we unexpectedly got the end-of-input.

ExpectedNumericToken

When this error variant is returned, a numeric token was expected, but a different token was present, or the end-of-input reached.

Fields

got: Option<u8>

Token read, or None if we unexpectedly got the end-of-input.

NumberError(NumberError)

An error variant for faults when parsing and constructing a number.

Trait Implementations

impl Clone for ErrorReason

fn clone(&self) -> ErrorReason

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorReason

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

Formats the value using the given formatter.

impl Display for ErrorReason

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

Formats the value using the given formatter.

impl Error for ErrorReason

fn source(&self) -> Option<&(dyn Error + 'static)>

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<NumberError> for ErrorReason

fn from(source: NumberError) -> Self

Converts to this type from the input type.

impl PartialEq for ErrorReason

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
