Struct StorageRouteState 

pub struct StorageRouteState {
    pub backend: Arc<dyn StorageBackend>,
    pub max_upload_bytes: usize,
    pub tenant_prefix: Option<String>,
    pub max_presign_expiry_secs: u64,
}

Shared state for all storage route handlers.

Fields

backend: Arc<dyn StorageBackend>

The configured storage backend (local, S3, GCS, Azure, …).

max_upload_bytes: usize

Maximum allowed upload body size in bytes.

Requests that exceed this limit are rejected with HTTP 413 before the body is forwarded to the backend, preventing memory exhaustion on the server when large files are sent.

tenant_prefix: Option<String>

Optional key prefix prepended to every storage key.

Used for per-tenant isolation: set this to the tenant’s ID so that tenant A’s keys ("tenantA/file.txt") are disjoint from tenant B’s ("tenantB/file.txt"). When None, keys are used as-is.

max_presign_expiry_secs: u64

Ceiling on a presigned URL’s requested validity, in seconds.

A presigned URL grants credential-free access to an object for its lifetime, so an unbounded expiry is a standing exposure. Requests for a longer validity are clamped down to this ceiling (L-presigned-expiry).

Implementations

impl StorageRouteState

pub fn new(backend: Arc<dyn StorageBackend>) -> Self

Create state with the given backend and the default 100 MiB upload limit.

pub const fn with_max_upload_bytes(self, bytes: usize) -> Self

Override the maximum upload size.

pub const fn with_max_presign_expiry_secs(self, secs: u64) -> Self

Override the ceiling on presigned-URL validity (in seconds).

pub fn with_tenant_prefix(self, prefix: impl Into<String>) -> Self

Set a tenant key prefix for per-tenant object isolation.

Every storage key is prefixed with {prefix}/ before being forwarded to the backend, ensuring that tenants cannot access each other’s objects even if they share the same bucket.

Trait Implementations

impl Clone for StorageRouteState

fn clone(&self) -> StorageRouteState

Returns a duplicate of the value.

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

Performs copy-assignment from source.
