Struct Decimal

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

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.

Source

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

Source

pub fn precision(&self) -> i32

Total number of decimal digits

Source

pub fn scale(&self) -> i32

Number of digits after the decimal point “.”

Source

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.
