Enum gcp_client::google::api::FieldBehavior

#[repr(i32)]pub enum FieldBehavior {
    Unspecified,
    Optional,
    Required,
    OutputOnly,
    InputOnly,
    Immutable,
}

An indicator of the behavior of a given field (for example, that a field is required in requests, or given as output but ignored as input). This does not change the behavior in protocol buffers itself; it only denotes the behavior and may affect how API tooling handles the field.

Note: This enum may receive new values in the future.

Variants

Unspecified

Conventional default for enums. Do not use this.

Optional

Specifically denotes a field as optional. While all fields in protocol buffers are optional, this may be specified for emphasis if appropriate.

Required

Denotes a field as required. This indicates that the field must be provided as part of the request, and failure to do so will cause an error (usually INVALID_ARGUMENT).

OutputOnly

Denotes a field as output only. This indicates that the field is provided in responses, but including the field in a request does nothing (the server must ignore it and must not throw an error as a result of the field's presence).

InputOnly

Denotes a field as input only. This indicates that the field is provided in requests, and the corresponding field is not included in output.

Immutable

Denotes a field as immutable. This indicates that the field may be set once in a request to create a resource, but may not be changed thereafter.

Implementations

impl FieldBehavior

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of FieldBehavior.

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

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

Trait Implementations

impl Clone for FieldBehavior

fn clone(&self) -> FieldBehavior

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for FieldBehavior

impl Debug for FieldBehavior

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

Formats the value using the given formatter.

impl Default for FieldBehavior

fn default() -> FieldBehavior

Returns the "default value" for a type.

impl Eq for FieldBehavior

impl From<FieldBehavior> for i32

fn from(value: FieldBehavior) -> i32

Performs the conversion.

impl Hash for FieldBehavior

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, 

Feeds a slice of this type into the given [Hasher].

impl Ord for FieldBehavior

fn cmp(&self, other: &FieldBehavior) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<FieldBehavior> for FieldBehavior

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<FieldBehavior> for FieldBehavior

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

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

#[must_use]fn lt(&self, other: &Rhs) -> bool

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

#[must_use]fn le(&self, other: &Rhs) -> bool

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

#[must_use]fn gt(&self, other: &Rhs) -> bool

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

#[must_use]fn ge(&self, other: &Rhs) -> bool
