Struct StaticUriProvider

pub struct StaticUriProvider { /* private fields */ }

A URI provider that is statically configured with the uEntity’s authority, entity ID and version.

Implementations

impl StaticUriProvider

pub fn new( authority: impl Into<String>, entity_id: u32, major_version: u8, ) -> Self

Creates a new URI provider from static information.

Arguments

• authority - The uEntity’s authority name.
• entity_id - The entity identifier.
• major_version - The uEntity’s major version.

Examples

use up_rust::{LocalUriProvider, StaticUriProvider};

let provider = StaticUriProvider::new("my-vehicle", 0x4210, 0x05);
assert_eq!(provider.get_authority(), "my-vehicle");

Trait Implementations

impl LocalUriProvider for StaticUriProvider

fn get_authority(&self) -> String

Gets the authority used for URIs representing this uEntity’s resources.

fn get_resource_uri(&self, resource_id: u16) -> UUri

Gets a URI that represents a given resource of this uEntity.

fn get_source_uri(&self) -> UUri

Gets the URI that represents the resource that this uEntity expects RPC responses and notifications to be sent to.

impl TryFrom<&UUri> for StaticUriProvider

fn try_from(source_uri: &UUri) -> Result<Self, Self::Error>

Creates a URI provider from a UUri.

Arguments

• source_uri - The UUri to take the entity’s authority, entity ID and version information from. The UUri’s resource ID is ignored.

Errors

Returns an error if the given UUri’s major version property is not a u8.

Examples

use up_rust::{LocalUriProvider, StaticUriProvider, UUri};

let source_uri = UUri::try_from("//my-vehicle/4210/5/0").unwrap();
assert!(StaticUriProvider::try_from(&source_uri).is_ok());

Invalid Major Version

use up_rust::{LocalUriProvider, StaticUriProvider, UUri};

let uuri_with_invalid_version = UUri {
  authority_name: "".to_string(),
  ue_id: 0x5430,
  ue_version_major: 0x1234, // not a u8
  resource_id: 0x0000,
  ..Default::default()
};
assert!(StaticUriProvider::try_from(uuri_with_invalid_version).is_err());

type Error = TryFromIntError

The type returned in the event of a conversion error.

impl TryFrom<UUri> for StaticUriProvider

type Error = TryFromIntError

The type returned in the event of a conversion error.

fn try_from(value: UUri) -> Result<Self, Self::Error>

Performs the conversion.
