pub struct Error { /* private fields */ }
Expand description
Error is the error struct returned by all opendal functions.
§Display
Error can be displayed in two ways:
- Via
Display
: likeerr.to_string()
orformat!("{err}")
Error will be printed in a single line:
Unexpected, context: { path: /path/to/file, called: send_async } => something wrong happened, source: networking error"
- Via
Debug
: likeformat!("{err:?}")
Error will be printed in multi lines with more details and backtraces (if captured):
Unexpected => something wrong happened
Context:
path: /path/to/file
called: send_async
Source: networking error
Backtrace:
0: opendal::error::Error::new
at ./src/error.rs:197:24
1: opendal::error::tests::generate_error
at ./src/error.rs:241:9
2: opendal::error::tests::test_error_debug_with_backtrace::{{closure}}
at ./src/error.rs:305:41
...
- For conventional struct-style Debug representation, like
format!("{err:#?}")
:
Error {
kind: Unexpected,
message: "something wrong happened",
status: Permanent,
operation: "Read",
context: [
(
"path",
"/path/to/file",
),
(
"called",
"send_async",
),
],
source: Some(
"networking error",
),
}
Implementations§
source§impl Error
impl Error
sourcepub fn new(kind: ErrorKind, message: impl Into<String>) -> Self
pub fn new(kind: ErrorKind, message: impl Into<String>) -> Self
Create a new Error with error kind and message.
sourcepub fn with_operation(self, operation: impl Into<&'static str>) -> Self
pub fn with_operation(self, operation: impl Into<&'static str>) -> Self
Update error’s operation.
§Notes
If the error already carries an operation, we will push a new context
(called, operation)
.
sourcepub fn with_context(self, key: &'static str, value: impl ToString) -> Self
pub fn with_context(self, key: &'static str, value: impl ToString) -> Self
Add more context in error.
sourcepub fn set_source(self, src: impl Into<Error>) -> Self
pub fn set_source(self, src: impl Into<Error>) -> Self
sourcepub fn set_permanent(self) -> Self
pub fn set_permanent(self) -> Self
Set permanent status for error.
sourcepub fn set_temporary(self) -> Self
pub fn set_temporary(self) -> Self
Set temporary status for error.
By set temporary, we indicate this error is retryable.
sourcepub fn set_persistent(self) -> Self
pub fn set_persistent(self) -> Self
Set persistent status for error.
By setting persistent, we indicate the retry should be stopped.
sourcepub fn is_temporary(&self) -> bool
pub fn is_temporary(&self) -> bool
Check if this error is temporary.
