Enum semver::ReqParseError

pub enum ReqParseError {

A ReqParseError is returned from methods which parse a string into a VersionReq. Each enumeration is one of the possible errors that can occur. VersionReq: struct.VersionReq.html

Variants

InvalidVersionRequirement

The given version requirement is invalid.

OpAlreadySet

You have already provided an operation, such as =, ~, or ^. Only use one.

InvalidSigil

The sigil you have written is not correct.

VersionComponentsMustBeNumeric

All components of a version must be numeric.

InvalidIdentifier

There was an error parsing an identifier.

MajorVersionRequired

At least a major version is required.

UnimplementedVersionRequirement

An unimplemented version requirement.

DeprecatedVersionRequirement(VersionReq)

This form of requirement is deprecated.

Trait Implementations

impl Clone for ReqParseError

fn clone(&self) -> ReqParseError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ReqParseError

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

Formats the value using the given formatter.

impl Display for ReqParseError

impl Error for ReqParseError

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

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<String> for ReqParseError

fn from(other: String) -> ReqParseError
