Enum object_store::ObjectStoreScheme

source ·
#[non_exhaustive]
pub enum ObjectStoreScheme { Local, Memory, AmazonS3, GoogleCloudStorage, MicrosoftAzure, Http, }
Expand description

Recognizes various URL formats, identifying the relevant ObjectStore

See ObjectStoreScheme::parse for more details

§Supported formats:

There are also special cases for AWS and Azure for https://{host?}/path paths:

  • dfs.core.windows.net, blob.core.windows.net, dfs.fabric.microsoft.com, blob.fabric.microsoft.com -> MicrosoftAzure
  • amazonaws.com -> AmazonS3
  • r2.cloudflarestorage.com -> AmazonS3

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Local

Url corresponding to LocalFileSystem

§

Memory

Url corresponding to InMemory

§

AmazonS3

Url corresponding to AmazonS3

§

GoogleCloudStorage

Url corresponding to GoogleCloudStorage

§

MicrosoftAzure

Url corresponding to MicrosoftAzure

§

Http

Url corresponding to HttpStore

Implementations§

source§

impl ObjectStoreScheme

source

pub fn parse(url: &Url) -> Result<(Self, Path), Error>

Create an ObjectStoreScheme from the provided Url

Returns the ObjectStoreScheme and the remaining Path

§Example
let url: Url = "file:///path/to/my/file".parse().unwrap();
let (scheme, path) = ObjectStoreScheme::parse(&url).unwrap();
assert_eq!(scheme, ObjectStoreScheme::Local);
assert_eq!(path.as_ref(), "path/to/my/file");

let url: Url = "https://blob.core.windows.net/path/to/my/file".parse().unwrap();
let (scheme, path) = ObjectStoreScheme::parse(&url).unwrap();
assert_eq!(scheme, ObjectStoreScheme::MicrosoftAzure);
assert_eq!(path.as_ref(), "path/to/my/file");

let url: Url = "https://example.com/path/to/my/file".parse().unwrap();
let (scheme, path) = ObjectStoreScheme::parse(&url).unwrap();
assert_eq!(scheme, ObjectStoreScheme::Http);
assert_eq!(path.as_ref(), "path/to/my/file");
