Trait Error

pub trait Error: Sized + StdError {
    // Required method
    fn custom<T: Display>(msg: T) -> Self;

    // Provided methods
    fn io_error(err: Error) -> Self { ... }
    fn invalid_data<T: Display>(msg: T) -> Self { ... }
    fn missing_data<T: Display>(msg: T) -> Self { ... }
}

Like serde the Error trait allows NixRead implementations to add custom error handling for NixDeserialize.

Required Methods

fn custom<T: Display>(msg: T) -> Self

A totally custom non-specific error.

Provided Methods

fn io_error(err: Error) -> Self

Some kind of std::io::Error occured.

fn invalid_data<T: Display>(msg: T) -> Self

The data read from NixRead is invalid. This could be that some bytes were supposed to be valid UFT-8 but weren’t.

fn missing_data<T: Display>(msg: T) -> Self

Required data is missing. This is mostly like an EOF

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.
