Expand description
Specification for the formatting of an argument in the format string.
Fields§
§fill: Option<char>
Optionally specified character to fill alignment with.
fill_span: Option<InnerSpan>
Span of the optionally specified fill character.
align: Alignment
Optionally specified alignment.
sign: Option<Sign>
The +
or -
flag.
alternate: bool
The #
flag.
zero_pad: bool
The 0
flag.
debug_hex: Option<DebugHex>
The x
or X
flag. (Only for Debug
.)
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).

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.
