Enum Operation 

#[non_exhaustive]
pub enum Operation {
    Read,
    Write,
    Create,
    Delete,
}

What can be done to a record.

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.

Read

See it.

Write

Change it.

Create

Make a new one. A new record is also written, so it takes Write too.

Delete

Take it away.

Trait Implementations

impl Clone for Operation

fn clone(&self) -> Operation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Eq for Operation

impl Ord for Operation

fn cmp(&self, other: &Operation) -> 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 PartialEq for Operation

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Operation

fn partial_cmp(&self, other: &Operation) -> 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
