Enum icu::pattern::PatternItemCow

source ·
pub enum PatternItemCow<'a, T> {
    Placeholder(T),
    Literal(Cow<'a, str>),
}
Expand description

A borrowed-or-owned item in a Pattern. Items are either string literals or placeholders.

Enabled with the alloc Cargo feature.

Variants§

§

Placeholder(T)

A placeholder of the type specified on this PatternItemCow.

§

Literal(Cow<'a, str>)

A string literal. This can occur in one of three places:

  1. Between the start of the string and the first placeholder (prefix)
  2. Between two placeholders (infix)
  3. Between the final placeholder and the end of the string (suffix)
