Struct ContextRule 

#[non_exhaustive]
pub struct ContextRule {
    pub selector: String,
    pub requested: Vec<String>,
    pub provided: Vec<String>,
    pub allowed_request_extensions: Vec<String>,
    pub allowed_response_extensions: Vec<String>,
    /* private fields */
}

A context rule provides information about the context for an individual API element.

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.

selector: String

Selects the methods to which this rule applies.

Refer to selector for syntax details.

requested: Vec<String>

A list of full type names of requested contexts, only the requested context will be made available to the backend.

provided: Vec<String>

A list of full type names of provided contexts. It is used to support propagating HTTP headers and ETags from the response extension.

allowed_request_extensions: Vec<String>

A list of full type names or extension IDs of extensions allowed in grpc side channel from client to backend.

allowed_response_extensions: Vec<String>

A list of full type names or extension IDs of extensions allowed in grpc side channel from backend to client.

Implementations

impl ContextRule

pub fn new() -> Self

pub fn set_selector<T: Into<String>>(self, v: T) -> Self

Sets the value of selector.

Example

let x = ContextRule::new().set_selector("example");

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

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

Sets the value of requested.

Example

let x = ContextRule::new().set_requested(["a", "b", "c"]);

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

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

Sets the value of provided.

Example

let x = ContextRule::new().set_provided(["a", "b", "c"]);

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

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

Sets the value of allowed_request_extensions.

Example

let x = ContextRule::new().set_allowed_request_extensions(["a", "b", "c"]);

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

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

Sets the value of allowed_response_extensions.

Example

let x = ContextRule::new().set_allowed_response_extensions(["a", "b", "c"]);

Trait Implementations

impl Clone for ContextRule

fn clone(&self) -> ContextRule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContextRule

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

Formats the value using the given formatter.

impl Default for ContextRule

fn default() -> ContextRule

Returns the “default value” for a type.

impl Message for ContextRule

fn typename() -> &'static str

The typename of this message.

impl PartialEq for ContextRule

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