Struct transact::error::InternalError
source ·
[−]pub struct InternalError { /* fields omitted */ }
Expand description
An error which is returned for reasons internal to the function.
This error is produced when a failure occurred within the function but the failure is due to an internal implementation detail of the function. This generally means that there is no specific information which can be returned that would help the caller of the function recover or otherwise take action.
Implementations
Constructs a new InternalError
from a specified source error.
The implementation of std::fmt::Display
for this error will simply pass through the
display of the source message unmodified.
Examples
use transact::error::InternalError;
let io_err = std::io::Error::new(std::io::ErrorKind::Other, "io error");
let internal_error = InternalError::from_source(Box::new(io_err));
assert_eq!(format!("{}", internal_error), "io error");
Constructs a new InternalError
from a specified source error and message string.
The implementation of std::fmt::Display
for this error will be the message string
provided.
Examples
use transact::error::InternalError;
let io_err = std::io::Error::new(std::io::ErrorKind::Other, "io error");
let internal_error = InternalError::from_source_with_message(Box::new(io_err), "oops".to_string());
assert_eq!(format!("{}", internal_error), "oops");
Constructs a new InternalError
from a specified source error and prefix string.
The implementation of std::fmt::Display
for this error will be constructed from the
prefix and source message’s display following the format of format!("{}: {}", prefix, source)
.
Examples
use transact::error::InternalError;
let io_err = std::io::Error::new(std::io::ErrorKind::Other, "io error");
let internal_error = InternalError::from_source_with_prefix(Box::new(io_err), "Could not open file".to_string());
assert_eq!(format!("{}", internal_error), "Could not open file: io error");
Constructs a new InternalError
with a specified message string.
The implementation of std::fmt::Display
for this error will be the message string
provided.
Examples
use transact::error::InternalError;
let internal_error = InternalError::with_message("oops".to_string());
assert_eq!(format!("{}", internal_error), "oops");
