Struct InMemoryStorage 

pub struct InMemoryStorage { /* private fields */ }

Available on crate feature storage and non-WebAssembly only.

In-memory storage backend

Implementations

impl InMemoryStorage

pub fn new( location: impl Into<String>, base_url: impl Into<String>, ) -> InMemoryStorage

Create a new in-memory storage backend

Examples

use reinhardt_utils::storage::InMemoryStorage;

let storage = InMemoryStorage::new("memory_root", "http://localhost/media");
assert_eq!(storage.base_location(), "memory_root");
assert_eq!(storage.base_url(), "http://localhost/media");

pub fn with_permissions( self, file_mode: Option<u32>, dir_mode: Option<u32>, ) -> InMemoryStorage

Set file and directory permission modes

Examples

use reinhardt_utils::storage::InMemoryStorage;

let storage = InMemoryStorage::new("memory_root", "http://localhost/media")
    .with_permissions(Some(0o644), Some(0o755));
assert_eq!(storage.file_permissions_mode(), Some(0o644));
assert_eq!(storage.directory_permissions_mode(), Some(0o755));

pub fn base_location(&self) -> &str

Get the base location path

Examples

use reinhardt_utils::storage::InMemoryStorage;

let storage = InMemoryStorage::new("my_location", "http://localhost/media");
assert_eq!(storage.base_location(), "my_location");

pub fn base_url(&self) -> &str

Get the base URL for file access

Examples

use reinhardt_utils::storage::InMemoryStorage;

let storage = InMemoryStorage::new("memory_root", "http://example.com/files");
assert_eq!(storage.base_url(), "http://example.com/files");

pub fn file_permissions_mode(&self) -> Option<u32>

Get the file permissions mode if set

Examples

use reinhardt_utils::storage::InMemoryStorage;

let storage = InMemoryStorage::new("memory_root", "http://localhost/media")
    .with_permissions(Some(0o644), None);
assert_eq!(storage.file_permissions_mode(), Some(0o644));

let storage_no_perms = InMemoryStorage::new("memory_root", "http://localhost/media");
assert_eq!(storage_no_perms.file_permissions_mode(), None);

pub fn directory_permissions_mode(&self) -> Option<u32>

Get the directory permissions mode if set

Examples

use reinhardt_utils::storage::InMemoryStorage;

let storage = InMemoryStorage::new("memory_root", "http://localhost/media")
    .with_permissions(None, Some(0o755));
assert_eq!(storage.directory_permissions_mode(), Some(0o755));

let storage_no_perms = InMemoryStorage::new("memory_root", "http://localhost/media");
assert_eq!(storage_no_perms.directory_permissions_mode(), None);

pub fn deconstruct(&self) -> (&str, (), HashMap<String, String>)

Deconstruct storage into components for serialization

Returns a tuple of (path, args, kwargs) compatible with Django storage conventions

Examples

use reinhardt_utils::storage::InMemoryStorage;

let storage = InMemoryStorage::new("memory_root", "http://localhost/media");
let (path, args, kwargs) = storage.deconstruct();
assert_eq!(path, "reinhardt_storage.InMemoryStorage");
assert_eq!(args, ());
assert_eq!(kwargs.get("location").unwrap(), "memory_root");
assert_eq!(kwargs.get("base_url").unwrap(), "http://localhost/media");
