Enum icu::locale::preferences::extensions::unicode::keywords::MeasurementSystem
source · #[non_exhaustive]pub enum MeasurementSystem {
Metric,
USSystem,
UKSystem,
}
Expand description
A Unicode Measurement System Identifier defines a preferred measurement system.
Specifying “ms” in a locale identifier overrides the default value specified by supplemental measurement system data for the region
The valid values are listed in LDML.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
Metric
Metric System
USSystem
US System of measurement: feet, pints, etc.; pints are 16oz
UKSystem
UK System of measurement: feet, pints, etc.; pints are 20oz

fn try_from_key_value( key: &Key, value: &Value, ) -> Result<Option<MeasurementSystem>, PreferencesParseError>

unicode extension key and if the key matches it attemptes to construct
the preference based on the given value.
If the value is not a valid value for the given key, the constructor throws.
