Struct FieldMeta 

pub struct FieldMeta {
    pub rust: &'static str,
    pub orig: &'static str,
    pub db: &'static str,
    pub as_: Option<&'static str>,
    pub tags: &'static [&'static str],
    pub omitempty_tags: &'static [&'static str],
    pub with_quote: bool,
}

Fields

rust: &'static str

Rust 字段名（用于生成取值代码）

orig: &'static str

用于 FieldMapper 的“原始字段名”（对齐 go 的 reflect.StructField.Name）。

Rust 无法获得运行时字段名；这里由宏生成，默认等于 rust， 但测试/用户可以显式指定以对齐 go 的 CamelCase 命名。

db: &'static str

SQL 列名（db tag / mapper 之后）

as_: Option<&'static str>

可选别名（AS）

tags: &'static [&'static str]

tags

omitempty_tags: &'static [&'static str]

omitempty tags（包含 “” 表示默认）

with_quote: bool

Implementations

impl FieldMeta

pub fn name_for_select(&self, flavor: Flavor, alias: &str) -> String

Trait Implementations

impl Clone for FieldMeta

fn clone(&self) -> FieldMeta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldMeta

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

Formats the value using the given formatter.

impl PartialEq for FieldMeta

fn eq(&self, other: &FieldMeta) -> 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.
