Enum Error 

#[non_exhaustive]
pub enum Error {
    Io(Error),
    Vendor(Box<dyn Error + Send + Sync + 'static>),
    Format(String),
    Conformance(String),
}

Stack-wide error type.

Vendor errors are erased into a boxed trait object so this enum does not change as vendor crates evolve. The enum is #[non_exhaustive]; match it with a wildcard arm.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Io(Error)

I/O failure (file not found, permission denied, short read, …).

Vendor(Box<dyn Error + Send + Sync + 'static>)

Vendor parser failed. The inner error is the vendor crate’s own error type, preserved via Box<dyn std::error::Error> so callers can downcast if they need vendor-specific context.

Format(String)

Format detection failed or the input does not match a supported vendor.

Conformance(String)

Conformance harness rejected a record stream.

Implementations

impl Error

pub fn vendor<E>(err: E) -> Self

where E: Error + Send + Sync + 'static,

Wrap a vendor-crate error into Error::Vendor.

Usable directly as a map_err argument: decode(scan).map_err(Error::vendor).

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
