Expand description
A complete description of how to format and parse a type.
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
Bytes that are formatted as-is.
Note: If you call the format
method that returns a String
, these bytes will be
passed through String::from_utf8_lossy
.
A minimal representation of a single non-literal item.
A series of literals or components that collectively form a partial or complete
description.
A FormatItem
that may or may not be present when parsing. If parsing fails, there
will be no effect on the resulting struct
.
This variant has no effect on formatting, as the value is guaranteed to be present.
A series of FormatItem
s where, when parsing, the first successful parse is used. When
formatting, the first element of the slice is used. An empty slice is a no-op when
formatting or parsing.
Performs copy-assignment from
source
.

sufficient, and should not be overridden without very good reason.
