Enum xvc_core::types::diff::Diff

pub enum Diff<T: Storable> {
    Identical,
    RecordMissing {
        actual: T,
    },
    ActualMissing {
        record: T,
    },
    Different {
        record: T,
        actual: T,
    },
    Skipped,
}

Shows which information is identical, missing or different in diff calculations.

We use this to compare anything that’s storable.

Variants

Identical

Both record and actual values are identical.

RecordMissing

Fields

actual: T

The actual value found (probably) in workspace

We don’t have the record, but we have the actual value

ActualMissing

Fields

record: T

The record value found in the stores

We have the record, but we don’t have the actual value

Different

Fields

record: T

The value found in store

actual: T

The value found in workspace

Both record and actual values are present, but they differ

Skipped

We skipped this comparison. It’s not an error, but it means we didn’t compare this field. It may be shortcutted, we don’t care or irrelevant.

Implementations

impl<T: Storable> Diff<T>

pub fn changed(&self) -> bool

Return true if the diff is not Diff::Identical or Diff::Skipped. This is used to find out if has changed.

Trait Implementations

impl<T: Clone + Storable> Clone for Diff<T>

fn clone(&self) -> Diff<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Storable> Debug for Diff<T>

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

Formats the value using the given formatter.

impl<T> Default for Diff<T>where T: Storable,

fn default() -> Self

Returns the “default value” for a type.

impl<'de, T> Deserialize<'de> for Diff<T>where for<'lt> T: Serialize + Deserialize<'lt> + Storable,

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

Deserialize this value from the given Serde deserializer.

impl<T: Hash + Storable> Hash for Diff<T>

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

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<T: Ord + Storable> Ord for Diff<T>

fn cmp(&self, other: &Diff<T>) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl<T: PartialEq + Storable> PartialEq<Diff<T>> for Diff<T>

fn eq(&self, other: &Diff<T>) -> 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.

impl<T: PartialOrd + Storable> PartialOrd<Diff<T>> for Diff<T>

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl<T> Serialize for Diff<T>where for<'lt> T: Serialize + Deserialize<'lt> + Storable,

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

Serialize this value into the given Serde serializer.

impl<T> Storable for Diff<T>where T: Storable,

fn type_description() -> String

A string representation for the type.
