Struct FormatOptions 

pub struct FormatOptions {
    pub number: NumberFormat,
    pub scientific: Scientific,
    pub precision: Option<usize>,
    pub separators: Separator,
    pub show_refs: ShowRefs,
}

Formatting options for values.

Fields

number: NumberFormat

How to format a number.

scientific: Scientific

Which suffix notation to use for scientific notation.

This option is ignored if number is not NumberFormat::Scientific.

precision: Option<usize>

The maximum number of digits to show. If None, the number is formatted with full precision.

This option might be useful when rendering floating-point numbers. Floating-point numbers in cas-rs have significantly higher precision than 32-bit / 64-bit floats; however, they are still subject to the same issues that can occur when performing floating-point arithmetic. The common solution to this is to trim off a small number of digits from the result.

Also, integers have arbitrary precision and are usually formatted completely. If this option is set and the integer has too many digits, it will be formatted in scientific notation as if it were a float.

This option does not control the precision of the number during calculation, only the number of digits to display during formatting.

separators: Separator

Whether to display separators for large numbers.

show_refs: ShowRefs

Whether to print addresses of reference types, such as lists.

This is useful for debugging, but can be confusing to an uninitiated user.

Implementations

impl FormatOptions

pub fn into_builder(self) -> FormatOptionsBuilder

Wraps the given FormatOptions into a builder for further customization.

Trait Implementations

impl Clone for FormatOptions

fn clone(&self) -> FormatOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FormatOptions

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

Formats the value using the given formatter.

impl Default for FormatOptions

fn default() -> FormatOptions

Returns the “default value” for a type.

impl PartialEq for FormatOptions

fn eq(&self, other: &FormatOptions) -> 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 FormatOptions
