Enum IdempotencyLevel

#[repr(i32)]
pub enum IdempotencyLevel {
    IdempotencyUnknown = 0,
    NoSideEffects = 1,
    Idempotent = 2,
}

Is this method side-effect-free (or safe in HTTP parlance), or idempotent, or neither? HTTP based RPC implementation may choose GET verb for safe methods, and PUT verb for idempotent methods instead of the default POST.

Variants

IdempotencyUnknown = 0

NoSideEffects = 1

implies idempotent

Idempotent = 2

idempotent, but may have side effects

Implementations

impl IdempotencyLevel

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of IdempotencyLevel.

pub fn from_i32(value: i32) -> Option<IdempotencyLevel>

Converts an i32 to a IdempotencyLevel, or None if value is not a valid variant.

Trait Implementations

impl Clone for IdempotencyLevel

fn clone(&self) -> IdempotencyLevel

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IdempotencyLevel

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

Formats the value using the given formatter.

impl Default for IdempotencyLevel

fn default() -> IdempotencyLevel

Returns the “default value” for a type.

impl From<IdempotencyLevel> for i32

fn from(value: IdempotencyLevel) -> i32

Converts to this type from the input type.

impl Hash for IdempotencyLevel

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 Ord for IdempotencyLevel

fn cmp(&self, other: &IdempotencyLevel) -> 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 IdempotencyLevel

fn eq(&self, other: &IdempotencyLevel) -> 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 PartialOrd for IdempotencyLevel

fn partial_cmp(&self, other: &IdempotencyLevel) -> 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.
