Implementations

impl Attachment

pub fn store( storage: &dyn Storage, prefix: &str, filename: &str, content_type: &str, data: &[u8], ) -> Result<Attachment, StorageError>

Store data under a new key below prefix.

pub fn store_stream( storage: &dyn Storage, prefix: &str, filename: &str, content_type: &str, reader: &mut dyn Read, ) -> Result<Attachment, StorageError>

Store everything reader yields (a streamed upload) under a new key below prefix; the size is counted as it’s read.

pub fn from_multipart( storage: &dyn Storage, prefix: &str, request: &Request, field: &str, ) -> Result<Option<Attachment>, StorageError>

Store the file uploaded in the multipart/form-data field field of request. Ok(None) when the request has no such field or it carries no file (no file name: an empty file input); Err for a body that isn’t multipart/form-data.

pub fn url(&self, storage: &dyn Storage) -> String

The file’s URL (Storage::url).

pub fn read(&self, storage: &dyn Storage) -> Result<Vec<u8>, StorageError>

The file’s bytes.

pub fn delete(&self, storage: &dyn Storage) -> Result<(), StorageError>

Delete the file.

pub fn encode(&self) -> String

The column text.

pub fn decode(text: &str) -> Option<Attachment>

Parse column text written by encode; None when it isn’t one (no key, a bad size or escape).
