Struct DebugDisplayFmt

pub struct DebugDisplayFmt<Fmt>(pub Fmt)
where
    Fmt: Fn(&mut Formatter<'_>) -> Result;

Implements Debug and Display by calling the stored closure.

Example

use fn_formats::DebugDisplayFmt;

let debug_display = DebugDisplayFmt(|f| write!(f, "debug or display"));

assert_eq!(format!("{:?}", debug_display), "debug or display");
assert_eq!(format!("{}", debug_display), "debug or display");

Trait Implementations

impl<Fmt> Clone for DebugDisplayFmt<Fmt>

where Fmt: Fn(&mut Formatter<'_>) -> Result + Clone,

fn clone(&self) -> DebugDisplayFmt<Fmt>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Fmt: Fn(&mut Formatter<'_>) -> Result> Debug for DebugDisplayFmt<Fmt>

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

Formats the value using the given formatter.

impl<Fmt> Default for DebugDisplayFmt<Fmt>

where Fmt: Fn(&mut Formatter<'_>) -> Result + Default,

fn default() -> DebugDisplayFmt<Fmt>

Returns the “default value” for a type.

impl<Fmt: Fn(&mut Formatter<'_>) -> Result> Display for DebugDisplayFmt<Fmt>

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

Formats the value using the given formatter.

impl<Fmt: Fn(&mut Formatter<'_>) -> Result> From<Fmt> for DebugDisplayFmt<Fmt>

let _: fn_formats::DebugDisplayFmt<_> = (|f: &mut core::fmt::Formatter| Ok(())).into();

fn from(fmt: Fmt) -> Self

Converts to this type from the input type.

impl<Fmt> Hash for DebugDisplayFmt<Fmt>

where Fmt: Fn(&mut Formatter<'_>) -> Result + Hash,

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<Fmt> Ord for DebugDisplayFmt<Fmt>

where Fmt: Fn(&mut Formatter<'_>) -> Result + Ord,

fn cmp(&self, other: &DebugDisplayFmt<Fmt>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<Fmt> PartialEq for DebugDisplayFmt<Fmt>

where Fmt: Fn(&mut Formatter<'_>) -> Result + PartialEq,

fn eq(&self, other: &DebugDisplayFmt<Fmt>) -> 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.

where Fmt: Fn(&mut Formatter<'_>) -> Result + PartialOrd,

fn partial_cmp(&self, other: &DebugDisplayFmt<Fmt>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
