Struct parity_scale_codec::Error

source · [−]

pub struct Error { /* private fields */ }

Expand description

Error type.

Descriptive on std environment, with chaining error on chain-error environment, underscriptive otherwise.

Implementations

source

impl Error

source

pub fn chain(self, desc: impl Into<Cow<'static, str>>) -> Self

Chain error message with description.

When compiled with chain-error feature, the description is chained, otherwise the description is ditched.

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
