JsonCtx

scratch_test_model::error

Struct JsonCtx 

pub struct JsonCtx<'a, E> { /* private fields */ }
Expand description

Combines an error with a json value that serves as context.

Typically, this json context is the input the function, that produced the error, received.

Implementations§

§

impl<'a, E> JsonCtx<'a, E>

pub fn inner_error(&self) -> &E

The wrapped error

pub fn json_ctx(&self) -> &Value

The json value that is related to the error. Normally, this will be the input to the function that produced the error.

pub fn into_inner(self) -> (E, &'a Value)

This consumes the JsonCtx and returns its parts as tuple so that they can be used further.

pub fn map_err<F>(self, m: impl FnOnce(E) -> F) -> JsonCtx<'a, F>

Wraps the error in a closure. It doesn’t change the context.
