Struct icu::datetime::provider::pattern::runtime::Pattern

source ·
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 PatternItems 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 PatternItems.

§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.

Implementations§
