Enum FlowSemantic 

pub enum FlowSemantic {
    Unknown,
    LocalCoordinates,
    AbsoluteCoordinates,
    LogicalPixels,
    PhysicalPixels,
}

Normalized semantic labels used by tooling when string contracts are too coarse to explain a mismatch (for example local vs absolute coordinates). 调试工具使用的规范化语义标签，避免仅凭字符串无法解释坐标域差异。

Variants

Unknown

Label no table entry knows; only literal equality is meaningful. 语义表不认识的标签；只有字面相等才有意义。

LocalCoordinates

Coordinates relative to the parent node. 相对于父节点的坐标。

AbsoluteCoordinates

Coordinates in the host’s absolute space. 宿主绝对空间中的坐标。

LogicalPixels

Device-independent pixel units. 设备无关的像素单位。

PhysicalPixels

Device pixel units. 设备像素单位。
