Struct DatasourceRef 

pub struct DatasourceRef(/* private fields */);

业务作用：携带经过统一校验的 datasource 身份，使各 driver 不依赖临时字符串解释名称。

Implementations

impl DatasourceRef

pub fn new(name: impl AsRef<str>) -> Result<Self>

业务作用：以既有兼容签名校验并固定一个 datasource qualifier。

参数说明：

• name：是配置边界或业务计划给出的数据源名。

返回：名称符合有界 canonical 合同时返回拥有型引用；失败时在 anyhow 错误链保留具名原因。

pub fn try_new(name: impl AsRef<str>) -> Result<Self, DatasourceNameError>

业务作用：为 checked 配置与事务入口校验 datasource qualifier 并保留结构化失败分类。

参数说明：

• name：是配置边界或业务计划给出的数据源名。

返回：名称符合有界 canonical 合同时返回拥有型引用，否则返回 DatasourceNameError。

pub fn default_ref() -> Self

业务作用：返回默认 datasource 的规范化身份。

参数说明: 无。

返回：名称固定为 default 的拥有型引用。

pub fn as_str(&self) -> &str

业务作用：读取 datasource 的规范化 qualifier。

参数说明: 无。

返回：与该引用同生命周期的名称切片。

Trait Implementations

impl AsRef<str> for DatasourceRef

impl Ord for DatasourceRef

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

impl PartialOrd for DatasourceRef

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.
