Enum PrecisionBehavior 

#[non_exhaustive]
pub enum PrecisionBehavior {
    AutoTruncate,
    Manual,
}

The behavior of a Displayable when a precision is set.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

AutoTruncate

Automatically truncate the formatted text to the number of characters specified as the precision.

This is the behavior specified in std::fmt for non-numeric types.

Manual

The precision will be manually handled (or ignored) by CustomDisplay::fmt() and CustomDisplay::width_in_chars().

Trait Implementations

impl Clone for PrecisionBehavior

fn clone(&self) -> PrecisionBehavior

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrecisionBehavior

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

Formats the value using the given formatter.

impl Display for PrecisionBehavior

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

Formats the value using the given formatter.

impl Hash for PrecisionBehavior

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for PrecisionBehavior

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