Enum si_scale::prefix::constraint::Constraint

pub enum Constraint {
    None,
    UnitOnly,
    UnitAndAbove,
    UnitAndBelow,
    Custom(Vec<Prefix>),
}

Specifies a constraint on the SI Prefix.

Variants

None

Allows all prefixes from Yocto to Yotta.

Note: having a None variant proves ergonomic in the context of this library.

UnitOnly

Only allows the Unit prefix, effectively preventing scaling.

UnitAndAbove

Only allows prefixes from Unit to Yotta.

UnitAndBelow

Only allows prefixes from Yocto to Unit.

Custom(Vec<Prefix>)

Only allows the specified prefixes (should be sorted in ascending exponent order).

Tuple Fields of Custom

0: Vec<Prefix>
