#[non_exhaustive]pub enum BorrowedFormatItem<'a> {
Literal(&'a [u8]),
Component(Component),
Compound(&'a [Self]),
Optional(&'a Self),
First(&'a [Self]),
}
Expand description
A complete description of how to format and parse a type.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Literal(&'a [u8])
Bytes that are formatted as-is.
Note: These bytes should be UTF-8, but are not required to be. The value is passed
through String::from_utf8_lossy
when necessary.
Component(Component)
A minimal representation of a single non-literal item.
Compound(&'a [Self])
A series of literals or components that collectively form a partial or complete description.
Optional(&'a 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(&'a [Self])
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.
