Trait SinkError

Source
pub trait SinkError: Sized {
    // Required method
    fn error_message<T: Display>(message: T) -> Self;

    // Provided methods
    fn error_io(err: Error) -> Self { ... }
    fn error_config(err: ConfigError) -> Self { ... }
}
Expand description

A trait that describes errors that can be reported by searchers and implementations of Sink.

Unless you have a specialized use case, you probably don’t need to implement this trait explicitly. It’s likely that using std::io::Error (which implements this trait) for your error type is good enough, largely because most errors that occur during search will likely be an std::io::Error.

Required Methods§

Source

fn error_message<T: Display>(message: T) -> Self

A constructor for converting any value that satisfies the std::fmt::Display trait into an error.

Provided Methods§

Source

fn error_io(err: Error) -> Self

A constructor for converting I/O errors that occur while searching into an error of this type.

By default, this is implemented via the error_message constructor.

Source

fn error_config(err: ConfigError) -> Self

A constructor for converting configuration errors that occur while building a searcher into an error of this type.

By default, this is implemented via the error_message constructor.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types§

Source§

impl SinkError for Box<dyn Error>

A Box<dyn std::error::Error> can be used as an error for Sink implementations out of the box.

Source§

fn error_message<T: Display>(message: T) -> Box<dyn Error>

Source§

impl SinkError for Error

An std::io::Error can be used as an error for Sink implementations out of the box.
