Enum time::format_description::FormatItem
source · [−]#[non_exhaustive]
pub enum FormatItem<'a> {
Literal(&'a [u8]),
Component(Component),
Compound(&'a [Self]),
Optional(&'a Self),
First(&'a [Self]),
}formatting or parsing only.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: 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(&'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 FormatItems 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.
