//! Physical dimension markers.
|
|
//!
|
|
//! Each marker is a zero sized type naming one physical dimension. A
|
|
//! [`Unit`](apsis_core::Unit) declares which dimension it measures through
|
|
//! its `Dimension` associated type, and conversion between quantities is
|
|
//! only permitted when the dimensions match.
|
|
//!
|
|
//! 物理量纲标记。
|
|
//!
|
|
//! 每个标记是一个零大小类型，命名一个物理量纲。[`Unit`](apsis_core::Unit)
|
|
//! 通过其 `Dimension` 关联类型声明所度量的量纲，量之间的换算仅在量纲相同时
|
|
//! 才被允许。
