Enum tarantool::tuple::TupleBuffer

pub enum TupleBuffer {
    Vector(Vec<u8>),
    TransactionScoped {
        ptr: NonNull<u8>,
        size: usize,
    },
}

Buffer containing tuple contents (MsgPack array)

If buffer is allocated within transaction: will be disposed after transaction ended (committed or dropped). If not: will act as a regular rust Vec<u8>

Variants

Vector(Vec<u8>)

TransactionScoped

Fields

ptr: NonNull<u8>

size: usize

Implementations

impl TupleBuffer

pub fn as_ptr(&self) -> *const u8

Get raw pointer to buffer.

pub fn len(&self) -> usize

Return the number of bytes used in memory by the tuple.

pub fn is_empty(&self) -> bool

pub unsafe fn from_vec_unchecked(buf: Vec<u8>) -> Self

Safety

buf must be a valid message pack array

pub fn try_from_vec(data: Vec<u8>) -> Result<Self>

Trait Implementations

impl AsRef<[u8]> for TupleBuffer

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Debug for TupleBuffer

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

Formats the value using the given formatter.

impl From<&'_ TupleBuffer> for Tuple

fn from(buf: &TupleBuffer) -> Self

Converts to this type from the input type.

impl From<Tuple> for TupleBuffer

fn from(t: Tuple) -> Self

Converts to this type from the input type.

impl TryFrom<Vec<u8, Global>> for TupleBuffer

type Error = Error

The type returned in the event of a conversion error.

fn try_from(data: Vec<u8>) -> Result<Self>

Performs the conversion.
