Struct icu::experimental::compactdecimal::provider::Pattern

pub struct Pattern<'data> {
    pub exponent: i8,
    pub index: u8,
    pub literal_text: Cow<'data, str>,
}

A compact decimal pattern, representing some literal text with an optional placeholder, and the power of 10 expressed by the text.

Fields

exponent: i8

The compact decimal exponent, e.g., 6 for “million”. The value 0 indicates that compact notation is not used; in that case, literal text must be empty; this corresponds to the CLDR pattern “0”. This is derived from the numbers of 0s in the pattern and the associated type attribute; it is a more convenient representation than the number of 0s, because it is often common to multiple types; for instance, the following correspond to the same Pattern: 0 M 00 M

index: u8

The index in literal_text before which the placeholder is inserted; this is 0 for insertion at the beginning, which is most common. The value 255 indicates that the pattern does not have a placeholder, as in French “mille” for 1000.

literal_text: Cow<'data, str>

The underlying CLDR pattern with the placeholder removed, e.g., “ M“ for the pattern “000 M”
