Trait QuantityUnit 

pub trait QuantityUnit: 'static {
    // Required methods
    fn type_id() -> TypeId;
    fn base_unit() -> &'static str;

    // Provided method
    fn allowed_suffixes() -> &'static [&'static str] { ... }
}

Marker trait describing the unit constraints of a Quantity.

Required Methods

fn type_id() -> TypeId

Stable identifier of this unit, embedded into the Quantity type id.

fn base_unit() -> &'static str

Canonical base unit (e.g. "kg", "m", "s", "B").

Provided Methods

fn allowed_suffixes() -> &'static [&'static str]

Suffixes accepted on input and rendered on output.

If empty, only QuantityUnit::base_unit is accepted. If non-empty, only the listed suffixes are accepted, so include the base unit here if it should remain valid.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
