Trait ResultLiquidChainExt 

pub trait ResultLiquidChainExt<T> {
    // Required methods
    fn chain<S: Into<Cow<'static, str>>>(self, msg: S) -> Result<T>;
    fn chain_with<F>(self, msg: F) -> Result<T>
       where F: FnOnce() -> Cow<'static, str>;
}

Result extension methods for adapting third party errors to Error.

Required Methods

fn chain<S: Into<Cow<'static, str>>>(self, msg: S) -> Result<T>

Create an Error with E as the cause.

fn chain_with<F>(self, msg: F) -> Result<T>

where F: FnOnce() -> Cow<'static, str>,

Create an Error with E as the cause.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
