Trait SqlError

pub trait SqlError: Sized {
    // Required methods
    fn fk_violation<E, F: FnOnce() -> E>(self, f: F) -> Result<Self, E>;
    fn unique_violation<E, F: FnOnce() -> E>(self, f: F) -> Result<Self, E>;
}

Trait for mapping certain postgres errors.

Required Methods

fn fk_violation<E, F: FnOnce() -> E>(self, f: F) -> Result<Self, E>

Map a foreign key violation to a different error type.

fn unique_violation<E, F: FnOnce() -> E>(self, f: F) -> Result<Self, E>

Map a unique violation to a different error type.

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.
