Enum si_scale::prefix::constraint::Constraint

source · [−]

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

Expand description

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).
