pub struct Pattern<'data> {
pub items: ZeroVec<'data, PatternItem>,
pub metadata: PatternMetadata,
}
Expand description
A raw, low-level pattern for datetime formatting.
It consists of an owned-or-borrowed list of PatternItem
s corresponding
to either fields or literal characters.
🚧 This code is considered unstable; it may change at any time, in breaking or non-breaking ways,
including in SemVer minor releases. While the serde representation of data structs is guaranteed
to be stable, their Rust representation might not be. Use with caution.
Fields§
§items: ZeroVec<'data, PatternItem>
The list of PatternItem
s.
metadata: PatternMetadata
Pre-computed metadata about the pattern.
This field should contain the smallest time unit from the items
vec.
If it doesn’t, unexpected results for day periods may be encountered.
