Struct clickhouse_srv::types::Decimal

pub struct Decimal { /* fields omitted */ }

Provides arbitrary-precision floating point decimal.

Implementations

impl Decimal

pub fn new(underlying: i64, scale: u8) -> Decimal

Method of creating a Decimal.

pub fn of<B: Base>(source: B, scale: u8) -> Decimal

pub fn internal<I: InternalResult>(&self) -> I

Get the internal representation of decimal as i32 or i64.

example:

      let mut c = pool.get_handle().await?;
      let block = c.query("SELECT toDecimal32(2, 4) AS x").fetch_all().await?;

      let x: Decimal = block.get(0, "x")?;
      let actual: i32 = x.internal();
      assert_eq!(20000, actual);

pub fn scale(&self) -> usize

Determines how many decimal digits fraction can have.
