Expand description
A complete description of how to format and parse a type.
Variants (Non-exhaustive)
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.
Literal(Box<[u8]>)
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
.
Component(Component)
A minimal representation of a single non-literal item.
Compound(Box<[Self]>)
A series of literals or components that collectively form a partial or complete description.
Optional(Box<Self>)
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.
First(Box<[Self]>)
A series of FormatItem
s where, when parsing, the first successful parse is used. When
formatting, the first element of the Vec
is used. An empty Vec
is a no-op when
formatting or parsing.
