Expand description

Specification for the formatting of an argument in the format string.

Fields

fill: Option<char>

Optionally specified character to fill alignment with.

align: Alignment

Optionally specified alignment.

flags: u32

Packed version of various flags provided.

precision: Count<'a>

The integer precision to use.

precision_span: Option<InnerSpan>

The span of the precision formatting flag (for diagnostics).

width: Count<'a>

The string width requested for the resulting format.

width_span: Option<InnerSpan>

The span of the width formatting flag (for diagnostics).

ty: &'a str

The descriptor string representing the name of the format desired for this argument, this can be empty or any number of characters, although it is required to be one word.

ty_span: Option<InnerSpan>

The span of the descriptor string (for diagnostics).

Performs copy-assignment from source. Read more
Formats the value using the given formatter. Read more
This method tests for self and other values to be equal, and is used by ==. Read more
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason. Read more

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.
