Trait DbErrorContext 

pub trait DbErrorContext<Output>: Sized {
    // Required method
    fn with_db_context<D>(self, context: impl FnOnce() -> D) -> Output
       where D: Display;

    // Provided method
    fn db_context<D>(self, context: D) -> Output
       where D: Display { ... }
}

Extension trait for .db_context() and .with_db_context()

Required Methods

fn with_db_context<D>(self, context: impl FnOnce() -> D) -> Output

where D: Display,

Returns the error, or result, with more context (from a closure)

If necessary, converts a rusqlite::Error to a DbSqlError.

Provided Methods

fn db_context<D>(self, context: D) -> Output

where D: Display,

Returns the error, or result, with more context

If necessary, converts a rusqlite::Error to a DbSqlError.

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.
