Struct TableSchema

pub struct TableSchema {
    pub name: String,
    pub schema: Option<String>,
    pub comment: Option<String>,
    pub indexes: Option<Vec<Index>>,
    pub columns: Vec<Column>,
    pub from: Option<String>,
    pub recreate: Option<String>,
    pub trim_columns: bool,

}

Fields

name: String

表名称

schema: Option<String>

表所属 schema

comment: Option<String>

说明信息

indexes: Option<Vec<Index>>

索引

columns: Vec<Column>

列

from: Option<String>

[控制字段] 从另外一个表重命名, 执行重命名的前提条件：1 该表不存在，2 from 指定的表必须存在

recreate: Option<String>

[控制字段] 删除并重建表，给出一个与该表关联的唯一重建标志 当 重建标志 标志第一次出现时，该表将会重建 重建会删除表内所有数据，请慎重使用

trim_columns: bool

[控制字段] 删除没有关联 struct 字段的表中的列

trim_indexes: bool

[控制字段] 删除未定义的索引

query_only: bool

[控制字段] 是否生成增删改相关函数 true 不生成 false 生成

Implementations

impl TableSchema

pub fn name_with_schema(&self) -> String

pub fn index_name_with_schema(&self, index_name: &String) -> String

pub fn check_indexes_columns(&self) -> Result<()>

检查索引列是否合法 有效索引列为表中列的字段名称

pub fn find_column(&self, name: &String) -> Option<Column>

pub fn assign(&mut self, source: TableSchema) -> Result<()>

合并 source 属性到当前 Table

pub fn add_index(&mut self, index: Index) -> Result<()>
