Trait ResultExt 

pub trait ResultExt<T> {
    // Required methods
    fn with_context<F>(self, f: F) -> Result<T, Error>
       where F: FnOnce() -> String;
    fn table_context(self, table: &str) -> Result<T, Error>;
    fn column_context(self, table: &str, column: &str) -> Result<T, Error>;
}

Extension trait for adding context to Results

Required Methods

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

where F: FnOnce() -> String,

Add context message on error

fn table_context(self, table: &str) -> Result<T, Error>

Add table context to error message

fn column_context(self, table: &str, column: &str) -> Result<T, Error>

Add table and column context to error message

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>
