Expand description

An enum representing the length of a field within a date or time formatting pattern string, in which the pattern field is represented as a letter occurring 1 or more times in a row, ex: MMM, dd, y. See the LDML documentation in UTS 35 for more details.

Variants§

§

One

Typical style is 1-2 digits. For numeric-only fields.

§

TwoDigit

Typical style is 2 digits. For numeric-only fields.

§

Abbreviated

Abbreviated (spellout) format.

§

Wide

Wide / Long / Full (spellout) format.

§

Narrow

Narrow / Long / Full (spellout) format.

§

Six

Meaning is field-dependent, for patterns that are 6 characters long. Ex: a Weekday pattern like EEEEEE means “Short”, but jjjjjj or CCCCCC for Hour may mean “Numeric hour (2 digits, zero pad if needed), narrow dayPeriod if used”. See the LDML documentation in UTS 35 for more details.

§

Fixed(u8)

A fixed size format for numeric-only fields that is at most 127 digits.

§

NumericOverride(FieldNumericOverrides)

FieldLength::One (numeric), but overridden with a different numbering system
