Struct Context 

#[non_exhaustive]
pub struct Context {
    pub name: String,
    pub display_name: String,
    pub etag: String,
    pub labels: HashMap<String, String>,
    pub create_time: Option<Timestamp>,
    pub update_time: Option<Timestamp>,
    pub parent_contexts: Vec<String>,
    pub schema_title: String,
    pub schema_version: String,
    pub metadata: Option<Struct>,
    pub description: String,
    /* private fields */
}

Available on crate features metadata-service or pipeline-service or schedule-service only.

Instance of a general context.

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.

name: String

Immutable. The resource name of the Context.

display_name: String

User provided display name of the Context. May be up to 128 Unicode characters.

etag: String

An eTag used to perform consistent read-modify-write updates. If not set, a blind “overwrite” update happens.

labels: HashMap<String, String>

The labels with user-defined metadata to organize your Contexts.

Label keys and values can be no longer than 64 characters (Unicode codepoints), can only contain lowercase letters, numeric characters, underscores and dashes. International characters are allowed. No more than 64 user labels can be associated with one Context (System labels are excluded).

create_time: Option<Timestamp>

Output only. Timestamp when this Context was created.

update_time: Option<Timestamp>

Output only. Timestamp when this Context was last updated.

parent_contexts: Vec<String>

Output only. A list of resource names of Contexts that are parents of this Context. A Context may have at most 10 parent_contexts.

schema_title: String

The title of the schema describing the metadata.

Schema title and version is expected to be registered in earlier Create Schema calls. And both are used together as unique identifiers to identify schemas within the local metadata store.

schema_version: String

The version of the schema in schema_name to use.

Schema title and version is expected to be registered in earlier Create Schema calls. And both are used together as unique identifiers to identify schemas within the local metadata store.

metadata: Option<Struct>

Properties of the Context. Top level metadata keys’ heading and trailing spaces will be trimmed. The size of this field should not exceed 200KB.

description: String

Description of the Context

Implementations

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Context

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

Formats the value using the given formatter.

impl Default for Context

fn default() -> Context

Returns the “default value” for a type.

impl Message for Context

fn typename() -> &'static str

The typename of this message.

impl PartialEq for Context

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