Trait Implementations

impl BlobDatabase for MemoryDatabase

fn record_upload(&mut self, record: &UploadRecord) -> Result<(), DbError>

Record a new upload. If the sha256 already exists for this pubkey, this is a no-op.

fn get_upload(&self, sha256: &str) -> Result<UploadRecord, DbError>

Get the upload record for a blob.

fn list_uploads_by_pubkey( &self, pubkey: &str, ) -> Result<Vec<UploadRecord>, DbError>

List uploads by a pubkey, ordered by created_at descending.

fn delete_upload(&mut self, sha256: &str) -> Result<bool, DbError>

Delete an upload record. Returns true if it existed.

fn get_or_create_user(&mut self, pubkey: &str) -> Result<UserRecord, DbError>

Get or create a user record.

fn set_quota( &mut self, pubkey: &str, quota_bytes: Option<u64>, ) -> Result<(), DbError>

Set a user’s quota limit. Pass None for unlimited.

fn check_quota( &self, pubkey: &str, additional_bytes: u64, ) -> Result<(), DbError>

Check if a user can upload additional_bytes within their quota. Returns Ok(()) if allowed, Err(DbError::QuotaExceeded) if not.

fn update_used_bytes( &mut self, pubkey: &str, used_bytes: u64, ) -> Result<(), DbError>

Update a user’s used_bytes (called after upload or delete).

fn record_access( &mut self, sha256: &str, bytes_served: u64, ) -> Result<(), DbError>

Record an access event (download) for a blob.

fn get_stats(&self, sha256: &str) -> Result<FileStats, DbError>

Get statistics for a blob.

fn upload_count(&self) -> usize

Total number of upload records.

fn user_count(&self) -> usize

Total number of registered users.

fn set_role(&mut self, pubkey: &str, role: &str) -> Result<(), DbError>

Set a user’s role (“admin”, “member”, or “denied”). Creates the user if they don’t exist.

fn get_role(&self, pubkey: &str) -> String

Get a user’s role. Returns “member” for unknown users.

fn list_users_by_role(&self, role: &str) -> Result<Vec<UserRecord>, DbError>

List all users with a given role.

fn find_by_phash(&self, phash: u64) -> Result<Vec<UploadRecord>, DbError>

Find uploads with a matching perceptual hash (for image dedup). Returns uploads whose phash matches within a Hamming distance threshold.

impl Default for MemoryDatabase

fn default() -> Self

Returns the “default value” for a type.
