Enum lexical_core::write_float_options::RoundMode

pub enum RoundMode {
    Round,
    Truncate,
}

Enumeration for how to round floats with precision control.

Variants

Round

Round to the nearest float string with the given number of significant digits.

Truncate

Truncate the float string with the given number of significant digits.

Implementations

impl RoundMode

pub const fn prefer_round_down(&self, significand: u64) -> bool

Determine if we should round down.

Trait Implementations

impl Clone for RoundMode

fn clone(&self) -> RoundMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RoundMode

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

Formats the value using the given formatter.

impl PartialEq for RoundMode

fn eq(&self, other: &RoundMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
