[−][src]Enum tarantool_module::tuple::TupleBuffer

pub enum TupleBuffer {
    Vector(Vec<u8>),
    TransactionScoped {
        ptr: *mut 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 of TransactionScoped

ptr: *mut u8size: usize

Implementations

impl TupleBuffer[src]

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

Get raw pointer to buffer.

pub fn len(&self) -> usize[src]

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