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) integers are used but this may be expanded in the future. The representation uses the endianness indicated in the Schema.

Implementations

impl<'a> Decimal<'a>

pub 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 const VT_PRECISION: VOffsetT

pub const VT_SCALE: VOffsetT

pub const VT_BITWIDTH: VOffsetT

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 width right now is 128 but this field exists for forward compatibility so that other bit widths may be supported in future format versions. 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<'a> Copy for Decimal<'a>

impl<'a> Debug for Decimal<'a>

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