Crate measurements

Measurements

Measurements is a crate that lets you represent physical quantities, such as Lengths, Masses, Pressures, etc. Each quantity has a series of functions that allow you to convert to and from common units. You can also perform arithmetic on the quantities - for example you can divide a Force by an Area to get a Pressure.

Modules

acceleration

Types and constants for handling acceleration.

angle

Types and constants for handling angles

angular_velocity

Types and constants for handling speed of rotation (angular velocity)

area

Types and constants for handling areas.

current

Types and constants for handling electrical current.

data

Types and constants for handling amounts of data (in octets, or bits).

density

Types and constants for handling density.

energy

Types and constants for handling energy.

force

Types and constants for handling force.

frequency

Types and constants for handling frequencies.

humidity

Types and constants for handling humidity.

length

Types and constants for handling lengths (or distances).

mass

Types and constants for handling masses.

power

Types and constants for handling power.

prelude

Traits that it is useful to have in scope. You should wildcard import this file.

pressure

Types and constants for handling pressure.

resistance

Types and constants for handling electrical resistance.

speed

Types and constants for handling speed.

temperature

Types and constants for handling temperature.

test_utils

Utility code for writing tests.

torque

Types and constants for handling torque

voltage

Types and constants for handling voltage.

volume

Types and constants for handling volumes (that is, three-dimensional space, not loudness).

Macros

implement_display

This is a special macro that creates the code to implement std::fmt::Display.

implement_measurement

This is a special macro that creates the code to implement operator and comparison overrides.

Structs

TorqueEnergy

If you multiply a Force by a Length, we can’t tell if you’re pushing something along (which requires Energy) or rotating something (which creates a Torque). This struct is what results from the multiplication, and you have to then convert it to whichever you want.

Traits

Measurement

All measurements implement this.
