Fields

name: String

结构体字段名称

column: Option<String>

数据库字段名称

col_type: Option<String>

数据库字段的数据类型，用于没有合适的类型时，可以自定义

typ: SqlType

数据库数据类型

ignore: bool

[控制字段] 是否忽略该字段， 在解析定义时，如果是 true 则不向列表中添加该列

pk: bool

主键 pk

autoincr: bool

自增类型 autoincr

comment: Option<String>

说明信息

nullable: bool

是否可为空 null | not-null

default: Option<String>

from: Option<String>

[控制字段] 从另外一个字段重命名, 执行重命名的前提条件：1 该字段不存在，2 from 指定的字段必须存在 重命名后如果字段属性不一致，则执行修改操作

replace: bool

[控制字段] 如果字段更新失败， replace 为 true 时，则删除旧字段并添加新字段 注意：删除旧字段会连带字段中的数据一起删除，并且不能恢复

Implementations

impl Column

pub fn is_name_equal(&self, col: &Column) -> bool

pub fn get_column_name(&self) -> String

pub fn get_query_column_name(&self) -> String

pub fn assign(&mut self, source: &Column)

Trait Implementations

impl Clone for Column

fn clone(&self) -> Column

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Column

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

Formats the value using the given formatter.

impl Default for Column

fn default() -> Column

Returns the “default value” for a type.

impl Parse for Column

fn parse(input: ParseStream<'_>) -> Result<Self>

impl PartialEq for Column

fn eq(&self, other: &Self) -> 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 ToTokens for Column

fn to_tokens(&self, tokens: &mut TokenStream)

Write self to the given TokenStream.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,

Convert self directly into a TokenStream object.
