Trait ResultExt 

pub trait ResultExt<T> {
    // Required methods
    fn with_context<F>(self, f: F) -> Result<T>
       where F: FnOnce() -> String;
    fn context(self, msg: &'static str) -> Result<T>;
}

Result extension trait for adding context to errors

Required Methods

fn with_context<F>(self, f: F) -> Result<T>

where F: FnOnce() -> String,

Add context to an error result

fn context(self, msg: &'static str) -> Result<T>

Add static context to an error result

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

impl<T, E> ResultExt<T> for Result<T, E>

where E: Into<ValknutError>,

ResultExt implementation for results with errors convertible to ValknutError.

fn with_context<F>(self, f: F) -> Result<T>

where F: FnOnce() -> String,

Adds dynamic context to an error result using a closure.

fn context(self, msg: &'static str) -> Result<T>

Adds static context to an error result.
