Trait datafusion_physical_expr_common::aggregate::tdigest::TryIntoF64

pub trait TryIntoF64 {
    // Required method
    fn try_as_f64(&self) -> Result<Option<f64>>;
}

This trait is implemented for each type a TDigest can operate on, allowing it to support both numerical rust types (obtained from PrimitiveArray instances), and ScalarValue instances.

Required Methods

fn try_as_f64(&self) -> Result<Option<f64>>

A fallible conversion of a possibly null self into a f64.

If self is null, this method must return Ok(None).

If self cannot be coerced to the desired type, this method must return an Err variant.
