Struct MigrateArgs 

pub struct MigrateArgs {
    pub rollback: bool,
    pub path: String,
    pub db_type: String,
    pub show_sql: bool,
    pub url: Option<String>,
}

migrate 命令参数

对齐 PHP php think migrate / php think migrate:rollback。

Fields

rollback: bool

回滚最后一批迁移（对齐 PHP migrate:rollback）

path: String

迁移目录（默认 migrations）

db_type: String

数据库类型（默认 postgres，对齐 sz-orm DbType）

影响迁移解析的方言处理。支持值： mysql / postgres / sqlite / oracle / mssql / oceanbase / dameng / kingbase 等（详见 DbType::from_str）。

show_sql: bool

打印每个迁移的 SQL 内容（dry-run 模式，便于审查）

url: Option<String>

数据库连接 URL（启用在线模式）

提供时连接数据库执行真实迁移；省略时为离线模式（仅列出待执行的 SQL）。 格式示例：

• PostgreSQL: postgres://user:pass@host:5432/dbname
• MySQL: mysql://user:pass@host:3306/dbname
• SQLite: sqlite://path/to/database.db

Trait Implementations

impl Args for MigrateArgs

fn group_id() -> Option<Id>

Report the ArgGroup::id for this set of arguments

fn augment_args<'b>(__clap_app: Command) -> Command

Append to Command so it can instantiate Self via FromArgMatches::from_arg_matches_mut

fn augment_args_for_update<'b>(__clap_app: Command) -> Command

Append to Command so it can instantiate self via FromArgMatches::update_from_arg_matches_mut

impl Debug for MigrateArgs

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

Formats the value using the given formatter.

impl FromArgMatches for MigrateArgs

fn from_arg_matches(__clap_arg_matches: &ArgMatches) -> Result<Self, Error>

Instantiate Self from ArgMatches, parsing the arguments as needed.

fn from_arg_matches_mut( __clap_arg_matches: &mut ArgMatches, ) -> Result<Self, Error>

Instantiate Self from ArgMatches, parsing the arguments as needed.

fn update_from_arg_matches( &mut self, __clap_arg_matches: &ArgMatches, ) -> Result<(), Error>
