Fields

width: Option<FormatCount>

The width. E.g. {:5} or {:width$}.

precision: Option<FormatCount>

The precision. E.g. {:.5} or {:.precision$}.

alignment: Option<FormatAlignment>

The alignment. E.g. {:>} or {:<} or {:^}.

fill: Option<char>

The fill character. E.g. the . in {:.>10}.

sign: Option<FormatSign>

The + or - flag.

alternate: bool

The # flag.

zero_pad: bool

The 0 flag. E.g. the 0 in {:02x}.

debug_hex: Option<FormatDebugHex>

The x or X flag (for Debug only). E.g. the x in {:x?}.

Trait Implementations

impl Clone for FormatOptions

fn clone(&self) -> FormatOptions

Returns a copy 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<__D: SpanDecoder> Decodable<__D> for FormatOptions

fn decode(__decoder: &mut __D) -> Self

impl Default for FormatOptions

fn default() -> FormatOptions

Returns the “default value” for a type.

impl<__E: SpanEncoder> Encodable<__E> for FormatOptions

fn encode(&self, __encoder: &mut __E)

impl PartialEq for FormatOptions

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Eq for FormatOptions

impl StructuralPartialEq for FormatOptions

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
