pub trait ToTupleBuffer {
// Required method
fn write_tuple_data(&self, w: &mut impl Write) -> Result<()>;
// Provided methods
fn to_tuple_buffer(&self) -> Result<TupleBuffer> { ... }
fn tuple_data(&self) -> Option<&[u8]> { ... }
}Expand description
Types implementing this trait can be converted to tarantool tuple (msgpack array).
Required Methods§
fn write_tuple_data(&self, w: &mut impl Write) -> Result<()>
Provided Methods§
fn to_tuple_buffer(&self) -> Result<TupleBuffer>
Sourcefn tuple_data(&self) -> Option<&[u8]>
fn tuple_data(&self) -> Option<&[u8]>
Returns a slice of bytes represeting the underlying tarantool tuple.
Returns None if Self doesn’t contain the data, in which case the
ToTupleBuffer::to_tuple_buffer should be used.
This method exists as an optimization for wrapper types to eliminate
extra copies, in cases where the implementing type already contains the
tuple data (e.g. TupleBuffer, RawBytes, etc.).
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.
