Struct Field 

pub struct Field<T> {
    pub name: &'static str,
    pub value: T,
}

A named field wrapping a value.

Carries the field name as a const string for introspection by generic algorithms (e.g., Diff output can include field names).

Fields

name: &'static str

The field name.

value: T

The field value.

Implementations

impl<T> Field<T>

pub fn new(name: &'static str, value: T) -> Self

Create a named field.

pub fn map<U>(self, f: impl FnOnce(T) -> U) -> Field<U>

Map the value.

Trait Implementations

impl<T: Clone> Clone for Field<T>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Field<T>

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

Formats the value using the given formatter.

impl<T: Diff> Diff for Field<T>

type Diff = <T as Diff>::Diff

The diff representation for this type.

fn diff(old: &Self, new: &Self) -> T::Diff

Compute the diff from old to new.

impl<T: Hash> Hash for Field<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: PartialEq> PartialEq for Field<T>

fn eq(&self, other: &Field<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: Patch> Patch for Field<T>

fn patch(old: &Self, diff: &T::Diff) -> Self

Apply the diff to old to produce new.

impl<T: Copy> Copy for Field<T>

impl<T: Eq> Eq for Field<T>

impl<T> StructuralPartialEq for Field<T>
