Struct Blob 

pub struct Blob<'c, 'p, P: Sqlite3BlobIo> { /* private fields */ }

RAII wrapper around an incremental blob handle.

The handle borrows the originating connection so blob operations cannot outlive the database handle.

Implementations

impl<'c, 'p, P: Sqlite3BlobIo> Blob<'c, 'p, P>

pub fn read(&self, buf: &mut [u8], offset: i32) -> Result<()>

Read from the blob into buf at offset.

pub fn write(&self, buf: &[u8], offset: i32) -> Result<()>

Write buf into the blob at offset.

pub fn len(&self) -> i32

Blob size in bytes.

pub fn is_empty(&self) -> bool

Whether the blob has zero length.

Trait Implementations

impl<'c, 'p, P: Sqlite3BlobIo> Drop for Blob<'c, 'p, P>

fn drop(&mut self)

Executes the destructor for this type.
