#[stack_trace_debug]
Expand description
Attribute macro to derive std::fmt::Debug for the annotated Error
type.
The generated Debug
implementation will print the error in a stack trace style. E.g.:
0: Foo error, at src/common/catalog/src/error.rs:80:10
1: Bar error, at src/common/function/src/error.rs:90:10
2: Root cause, invalid table name, at src/common/catalog/src/error.rs:100:10
Notes on using this macro:
#[snafu(display)]
must present on each enum variants, and should not includelocation
andsource
.- Only our internal error can be named
source
. All external error should beerror
with an#[snafu(source)]
annotation. common_error
crate must be accessible.
