Enum FlexDirection 

pub enum FlexDirection {
    Row,
    Column,
    RowReverse,
    ColumnReverse,
}

重导出样式类型（Style、Display、Position 等） flexbox 布局主轴的方向。

总是有两个垂直的布局轴：主（或主要）和交叉（或次要）。 添加项目将导致它们沿主轴彼此相邻定位。 通过在整个树中变化此值，你可以创建复杂的轴对齐布局。

项目始终相对于交叉轴对齐，并相对于主轴对齐。

默认行为是 FlexDirection::Row。

Trait Implementations

impl Clone for FlexDirection

fn clone(&self) -> FlexDirection

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for FlexDirection

impl Debug for FlexDirection

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FlexDirection

fn default() -> FlexDirection

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FlexDirection

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for FlexDirection

impl From<FlexDirection> for FlexDirection

fn from(value: FlexDirection) -> Self

Converts to this type from the input type.

impl JsonSchema for FlexDirection

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for FlexDirection

fn eq(&self, other: &FlexDirection) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for FlexDirection

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
