Enum HydrationError 

pub enum HydrationError {
    SingleScalarRequiresSingleRow {
        actual_rows: usize,
    },
    ColumnNotFound {
        column: String,
    },
    EmptyRow,
    Internal(String),
}

Hydration 错误

Variants

SingleScalarRequiresSingleRow

SingleScalar 模式下行数不等于 1

Fields

actual_rows: usize

ColumnNotFound

指定列不存在

Fields

column: String

EmptyRow

行列数为 0

Internal(String)

P0 修复：内部解析不变量违反（不应触发，触发说明逻辑有 bug）

Trait Implementations

impl Clone for HydrationError

fn clone(&self) -> HydrationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HydrationError

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

Formats the value using the given formatter.

impl Display for HydrationError

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

Formats the value using the given formatter.

impl Error for HydrationError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for HydrationError

fn eq(&self, other: &HydrationError) -> bool

Equality operator ==.

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

Inequality operator !=.
