Enum ParseVersionError 

#[non_exhaustive]
pub enum ParseVersionError {
    Empty,
    MissingComponent {
        component: &'static str,
    },
    InvalidNumber {
        component: &'static str,
    },
    LeadingZero {
        component: &'static str,
    },
    InvalidIdentifier,
    InvalidComparator,
}

Why a version or a version requirement could not be parsed.

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.

Empty

The text is empty or only whitespace.

MissingComponent

A part is missing: "1.2" has no patch.

Fields

component: &'static str

"minor" or "patch".

InvalidNumber

A part is not a number (or does not fit a u64).

Fields

component: &'static str

"major", "minor" or "patch".

LeadingZero

A number has a leading zero ("01"), which semver forbids.

Fields

component: &'static str

"major", "minor", "patch" or "prerelease" (a numeric identifier).

InvalidIdentifier

A pre-release or build identifier is empty or has a character outside [0-9A-Za-z-].

InvalidComparator

A requirement comparator is malformed: unknown operator, a wildcard where it is not allowed, a pre-release on a partial version, or build metadata.

Trait Implementations

impl Clone for ParseVersionError

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 ParseVersionError

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

Formats the value using the given formatter.

impl Display for ParseVersionError

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

Formats the value using the given formatter.

impl Eq for ParseVersionError

impl Error for ParseVersionError

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 ParseVersionError

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

Equality operator ==.

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

Inequality operator !=.
