Enum ProbeFailure 

#[non_exhaustive]
pub enum ProbeFailure {
    Io(Error),
    Exit {
        status: ExitStatus,
        stderr: String,
    },
    Json(Error),
    Schema(&'static str),
}

Why Cargo could not report the storage roots for an invocation.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Io(Error)

Cargo could not be started or its output could not be read.

Exit

Cargo exited unsuccessfully; stderr contains a bounded tail of its output.

Fields

status: ExitStatus

Cargo’s process exit status.

stderr: String

The last five non-empty stderr lines, limited to 1 KiB.

Json(Error)

Cargo’s stdout was not valid metadata JSON.

Schema(&'static str)

A required metadata field was missing or was not a string.

Trait Implementations

impl Debug for ProbeFailure

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ProbeFailure

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ProbeFailure

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
