Struct DecodeError 

pub struct DecodeError {
    pub column: Cow<'static, str>,
    pub expected: &'static str,
    pub actual: Cow<'static, str>,
    /* private fields */
}

Row/column decoding failure.

Fields

column: Cow<'static, str>

expected: &'static str

actual: Cow<'static, str>

Implementations

impl DecodeError

pub fn with_source( column: impl Into<Cow<'static, str>>, expected: &'static str, actual: impl Into<Cow<'static, str>>, source: impl Error + Send + Sync + 'static, ) -> BsqlError

Create a decode error with an underlying cause.

pub fn column_count(expected: usize, actual: usize) -> BsqlError

Create a decode error for a column count mismatch.

Used by generated code to detect schema drift between compile-time and runtime (e.g. a column was added/removed after the binary was built).

Trait Implementations

impl Debug for DecodeError

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

Formats the value using the given formatter.

impl Display for DecodeError

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

Formats the value using the given formatter.

impl Error for DecodeError

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.
