Struct LobWriter 

pub struct LobWriter { /* private fields */ }

A byte-oriented lazy writer over a (typically temporary) BLOB locator. Each write_chunk appends at the running byte cursor.

Implementations

impl LobWriter

pub fn new(locator: Vec<u8>) -> Self

Start a writer at the beginning of locator.

pub fn locator(&self) -> &[u8]

The (possibly server-updated) locator.

pub fn into_locator(self) -> Vec<u8>

Consume the writer, returning its locator (e.g. to free the temp LOB).

pub async fn write_chunk( &mut self, conn: &mut Connection, cx: &Cx, data: &[u8], ) -> Result<()>

Append data at the current byte cursor. A write may return an updated locator (temporary LOBs), which is adopted for subsequent writes.

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

Performs copy-assignment from source.

impl Debug for LobWriter

fn fmt(&self, f: &mut Formatter<'_>) -> Result
