Struct tarantool::tuple::TupleBuffer

pub struct TupleBuffer(/* private fields */);

TupleBuffer Buffer containing tuple contents (MsgPack array)

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 Clone for TupleBuffer

fn clone(&self) -> TupleBuffer

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TupleBuffer

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TupleBuffer

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

impl From<&Tuple> for TupleBuffer

fn from(t: &Tuple) -> Self

Converts to this type from the input type.

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 From<TupleBuffer> for Vec<u8>

fn from(b: TupleBuffer) -> Self

Converts to this type from the input type.

impl<L> LuaRead<L> for TupleBuffer

where L: AsLua,

fn lua_read_at_position(lua: L, index: NonZeroI32) -> ReadResult<Self, L>

Reads the data from Lua at a given position.

fn n_values_expected() -> i32

fn lua_read(lua: L) -> Result<Self, (L, WrongType)>

Reads the data from Lua.

fn lua_read_at_maybe_zero_position( lua: L, index: i32 ) -> Result<Self, (L, WrongType)>

where L: AsLua,

impl PartialEq for TupleBuffer

fn eq(&self, other: &TupleBuffer) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Return for TupleBuffer

fn ret(self, ctx: FunctionCtx) -> c_int

impl Serialize for TupleBuffer

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

impl ToTupleBuffer for TupleBuffer

fn to_tuple_buffer(&self) -> Result<TupleBuffer>

fn tuple_data(&self) -> Option<&[u8]>

Returns a slice of bytes represeting the underlying tarantool tuple.

fn write_tuple_data(&self, w: &mut impl Write) -> Result<()>

impl TryFrom<Vec<u8>> 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.
