Struct rustc_builtin_macros::format::ast::FormatOptions

pub struct FormatOptions {
    pub width: Option<FormatCount>,
    pub precision: Option<FormatCount>,

}

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}.

flags: u32

The +, -, 0, #, x? and X? flags.

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 Default for FormatOptions

fn default() -> FormatOptions

Returns the “default value” for a type.

impl PartialEq<FormatOptions> 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 StructuralEq 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.
