Struct Metadata 

#[non_exhaustive]
pub struct Metadata {
    pub fingerprint: Option<Bytes>,
    pub items: Vec<Items>,
    pub kind: Option<String>,
    /* private fields */
}

Available on crate features instance-templates or instances or machine-images or projects or region-instance-templates or region-instances only.

A metadata key/value entry.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

fingerprint: Option<Bytes>

Specifies a fingerprint for this request, which is essentially a hash of the metadata’s contents and used for optimistic locking. The fingerprint is initially generated by Compute Engine and changes after every request to modify or update metadata. You must always provide an up-to-date fingerprint hash in order to update or change metadata, otherwise the request will fail with error412 conditionNotMet.

To see the latest fingerprint, make a get() request to retrieve the resource.

items: Vec<Items>

Array of key/value pairs. The total size of all keys and values must be less than 512 KB.

kind: Option<String>

[Output Only] Type of the resource. Always compute#metadata for metadata.

Implementations

impl Metadata

pub fn new() -> Self

pub fn set_fingerprint<T>(self, v: T) -> Self

where T: Into<Bytes>,

Sets the value of fingerprint.

pub fn set_or_clear_fingerprint<T>(self, v: Option<T>) -> Self

where T: Into<Bytes>,

Sets or clears the value of fingerprint.

pub fn set_items<T, V>(self, v: T) -> Self

where T: IntoIterator<Item = V>, V: Into<Items>,

Sets the value of items.

pub fn set_kind<T>(self, v: T) -> Self

where T: Into<String>,

Sets the value of kind.

pub fn set_or_clear_kind<T>(self, v: Option<T>) -> Self

where T: Into<String>,

Sets or clears the value of kind.

Trait Implementations

impl Clone for Metadata

fn clone(&self) -> Metadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Metadata

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

Formats the value using the given formatter.

impl Default for Metadata

fn default() -> Metadata

Returns the “default value” for a type.

impl Message for Metadata

fn typename() -> &'static str

The typename of this message.

impl PartialEq for Metadata

fn eq(&self, other: &Metadata) -> 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.
