Enum ResolveVersion 

#[non_exhaustive]
#[repr(u32)]
pub enum ResolveVersion {
    V1 = 1,
    V2 = 2,
    V3 = 3,
    V4 = 4,
}

Lockfile versions

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.

V1 = 1

Original Cargo.lock format which places checksums in the [[metadata]] table.

V2 = 2

Revised Cargo.lock format which is optimized to prevent merge conflicts.

For more information, see: https://github.com/rust-lang/cargo/pull/7070

V3 = 3

Encodes Git dependencies with branch = 'master' in the manifest as ?branch=master in their URLs.

For more information, see: https://internals.rust-lang.org/t/upcoming-changes-to-cargo-lock/14017

V4 = 4

SourceId URL serialization is aware of URL encoding.

Trait Implementations

impl Clone for ResolveVersion

fn clone(&self) -> ResolveVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResolveVersion

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

Formats the value using the given formatter.

impl Default for ResolveVersion

V3 format is now the default.

fn default() -> ResolveVersion

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ResolveVersion

fn deserialize<__D>( __deserializer: __D, ) -> Result<ResolveVersion, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<ResolveVersion> for u32

fn from(version: ResolveVersion) -> u32

Converts to this type from the input type.

impl FromStr for ResolveVersion

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<ResolveVersion, Error>

Parses a string s to return a value of this type.

impl Hash for ResolveVersion

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ResolveVersion

fn cmp(&self, other: &ResolveVersion) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ResolveVersion

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

Tests for self and other values to be equal, and is used by ==.

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

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

fn partial_cmp(&self, other: &ResolveVersion) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for ResolveVersion

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<u32> for ResolveVersion

type Error = Error

The type returned in the event of a conversion error.

fn try_from(num: u32) -> Result<ResolveVersion, Error>

Performs the conversion.

impl Copy for ResolveVersion
