Required Methods

fn with_context_internal_error( self, message: impl FnOnce() -> String, ) -> Result<T, ApiError>

Make a new internal server error using the given function to create the message.

fn with_context_bad_request( self, message: impl FnOnce() -> String, ) -> Result<T, ApiError>

Make a new bad request error using the given function to create the message.

fn with_context_not_found( self, message: impl FnOnce() -> String, ) -> Result<T, ApiError>

Make a new not found error using the given function to create the message.

Provided Methods

fn context_internal_error(self, message: &str) -> Result<T, ApiError>

where Self: Sized,

Make a new internal server error with the given message.

fn context_bad_request(self, message: &str) -> Result<T, ApiError>

where Self: Sized,

Make a new bad request error with the given message.

fn context_not_found(self, message: &str) -> Result<T, ApiError>

where Self: Sized,

Make a new not found error with the given 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.
