Enum Precision 

pub enum Precision {
    MostCommon,
    Maximum,
}

Policy for resolving the per-currency display precision from the observed distribution.

Matches Python beancount.core.display_context.Precision:

• MostCommon returns the mode of the dp histogram. Used by bean-query for its result tables. Outliers (a single 28-decimal price annotation, a single integer-valued cost amid mostly 2dp postings) don’t dominate.
• Maximum returns the highest dp ever observed for the currency. Used by Python display_context when rendering prices, where preserving the highest-precision sample is the explicit goal.

Default is MostCommon to match bean-query’s default rendering of position/amount columns. See PR #985 follow-up and beanquery#275 for the upstream conversation.

Variants

MostCommon

Mode of the per-currency distribution (Python MOST_COMMON).

Maximum

Maximum dp ever observed (Python MAXIMUM).

Trait Implementations

impl Clone for Precision

fn clone(&self) -> Precision

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Precision

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

Formats the value using the given formatter.

impl Default for Precision

fn default() -> Precision

Returns the “default value” for a type.

impl PartialEq for Precision

fn eq(&self, other: &Precision) -> 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.

impl Copy for Precision

impl Eq for Precision

impl StructuralPartialEq for Precision
