Trait ValknutResultExt 

pub trait ValknutResultExt<T> {
    // Required methods
    fn map_io_err(self, message: impl Into<String>) -> Result<T>;
    fn map_json_err(self, context: impl Into<String>) -> Result<T>;
    fn map_generic_err(self, operation: impl Into<String>) -> Result<T>;
}

Extension trait for common error mapping patterns

Required Methods

fn map_io_err(self, message: impl Into<String>) -> Result<T>

Map I/O errors with a custom message

fn map_json_err(self, context: impl Into<String>) -> Result<T>

Map JSON parsing errors with context

fn map_generic_err(self, operation: impl Into<String>) -> Result<T>

Map generic errors with operation context

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> ValknutResultExt<T> for Result<T, E>
