Struct arrow_ipc::gen::Schema::Decimal

pub struct Decimal<'a> {
    pub _tab: Table<'a>,
}

Exact decimal value represented as an integer value in two’s complement. Currently only 128-bit (16-byte) and 256-bit (32-byte) integers are used. The representation uses the endianness indicated in the Schema.

Implementations

impl<'a> Decimal<'a>

pub const VT_PRECISION: VOffsetT = 4u16

pub const VT_SCALE: VOffsetT = 6u16

pub const VT_BITWIDTH: VOffsetT = 8u16

pub unsafe fn init_from_table(table: Table<'a>) -> Self

pub fn create<'bldr: 'args, 'args: 'mut_bldr, 'mut_bldr>(
    _fbb: &'mut_bldr mut FlatBufferBuilder<'bldr>,
    args: &'args DecimalArgs
) -> WIPOffset<Decimal<'bldr>>

pub fn precision(&self) -> i32

Total number of decimal digits

pub fn scale(&self) -> i32

Number of digits after the decimal point “.”

pub fn bitWidth(&self) -> i32

Number of bits per value. The only accepted widths are 128 and 256. We use bitWidth for consistency with Int::bitWidth.

Trait Implementations

impl<'a> Clone for Decimal<'a>

fn clone(&self) -> Decimal<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Decimal<'_>

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

Formats the value using the given formatter.

impl<'a> Follow<'a> for Decimal<'a>

type Inner = Decimal<'a>

unsafe fn follow(buf: &'a [u8], loc: usize) -> Self::Inner

Safety

impl<'a> PartialEq<Decimal<'a>> for Decimal<'a>

fn eq(&self, other: &Decimal<'a>) -> 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 Verifiable for Decimal<'_>

fn run_verifier(
    v: &mut Verifier<'_, '_>,
    pos: usize
) -> Result<(), InvalidFlatbuffer>

Runs the verifier for this type, assuming its at position pos in the verifier’s buffer. Should not need to be called directly.
