Trait WithError 

pub trait WithError {
    // Required method
    fn with_error<T>(operation: impl FnOnce() -> T) -> Result<T, Error>;
}

Available on crate features internal-api-crypto and internal-with-error only.

Adds error support to operations with an infallible signature.

Required Methods

fn with_error<T>(operation: impl FnOnce() -> T) -> Result<T, Error>

Executes a seemingly infallible operation with error support.

The closure may actually call multiple seemingly infaillible operations. Each such call should support running after a previous one failed. This funtion returns an error if any such call failed.

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.
