pub struct JoinBuilder { /* private fields */ }Expand description
JOIN 构造器（已指定 JOIN 类型，待指定右表）
Implementations§
Source§impl JoinBuilder
impl JoinBuilder
Sourcepub fn new(kind: JoinKind) -> JoinBuilder
pub fn new(kind: JoinKind) -> JoinBuilder
创建新的 JoinBuilder，指定 JOIN 类型
Sourcepub fn table<T>(self) -> JoinOnwhere
T: TypedTable,
pub fn table<T>(self) -> JoinOnwhere
T: TypedTable,
指定 JOIN 的右表（被 join 进来的表）
返回 JoinOn，等待 ON 条件。
CROSS JOIN 无需 ON 条件，可直接调用 JoinOn::build。
