Struct NoMerge

pub struct NoMerge<T>(pub T);

An unmergeable value.

This wrapper can wrap any type and make it “unmergeable”. This means that any attempt to merge it will result in a collision error.

Example

let a = NoMerge(vec![0, 1]);
let b = NoMerge(vec![2]);

let err = a.merge(b).unwrap_err();

assert_eq!(err.kind, ErrorKind::Collision);

serde

This type deserializes like T.

Mutably dereferences the value.

impl<'de, T> Deserialize<'de> for NoMerge<T>

where T: Deserialize<'de>,

Available on crate feature serde only.

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> From<T> for NoMerge<T>

fn from(x: T) -> Self

Converts to this type from the input type.

impl<T: Hash> Hash for NoMerge<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> Merge for NoMerge<T>

fn merge(self, _other: Self) -> Result<Self, Error>

Merge self with other.

fn merge_ref(&mut self, _other: Self) -> Result<(), Error>

Merge self with other without taking ownership of self.

impl<T: Ord> Ord for NoMerge<T>

fn cmp(&self, other: &NoMerge<T>) -> 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.

where Self: Sized,

Restrict a value to a certain interval.

impl<T: PartialEq> PartialEq for NoMerge<T>

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

impl<T: PartialOrd> PartialOrd for NoMerge<T>

fn partial_cmp(&self, other: &NoMerge<T>) -> 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.
