provider only.Expand description
Trait that will transform the data to be saved in the DB in a (ideally) compressed format
Required Associated Types§
Required Methods§
fn compress_to_buf<B>(&self, buf: &mut B)
fn compress_to_buf<B>(&self, buf: &mut B)
Compresses data to a given buffer.
Provided Methods§
fn uncompressable_ref(&self) -> Option<&[u8]>
fn uncompressable_ref(&self) -> Option<&[u8]>
If the type cannot be compressed, return its inner reference as Some(self.as_ref())
fn compress(self) -> Self::Compressed
fn compress(self) -> Self::Compressed
Compresses data going into the database.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
