Struct wasmcloud_runtime::capability::wrpc::wasi::io::error::Error
source · pub struct Error(/* private fields */);Expand description
A resource which represents some error information.
The only method provided by this resource is to-debug-string,
which provides some human-readable information about the error.
In the wasi:io package, this resource is returned through the
wasi:io/streams/stream-error type.
To provide more specific error information, other interfaces may
provide functions to further “downcast” this error into more specific
error information. For example, errors returned in streams derived
from filesystem types to be described using the filesystem’s own
error-code type, using the function
wasi:filesystem/types/filesystem-error-code, which takes a parameter
borrow<error> and returns
option<wasi:filesystem/types/error-code>.
The set of functions which can “downcast” an error into a more
concrete type is open.
Implementations§
source§impl Error
impl Error
sourcepub fn to_debug_string<'a, C: Invoke>(
wrpc__: &'a C,
cx__: C::Context,
self_: &'a ResourceBorrow<Error>,
) -> impl Future<Output = Result<String>> + Send + 'a
pub fn to_debug_string<'a, C: Invoke>( wrpc__: &'a C, cx__: C::Context, self_: &'a ResourceBorrow<Error>, ) -> impl Future<Output = Result<String>> + Send + 'a
Returns a string that is suitable to assist humans in debugging this error.
WARNING: The returned string should not be consumed mechanically! It may change across platforms, hosts, or other implementation details. Parsing this string is a major platform-compatibility hazard.
