Enum ToolError 

pub enum ToolError {
    InvalidInvocation(InvalidInvocation),
    Io(Error),
    NotExecutable,
    Artifact(ArtifactError),
    Execution(Box<ExecutionError>),
    VersionUtf8 {
        source: Utf8Error,
        evidence: Box<ExecutionEvidence>,
    },
    VersionMismatch {
        evidence: Box<ExecutionEvidence>,
    },
}

Executable admission or execution failed.

Variants

InvalidInvocation(InvalidInvocation)

Invalid context, authority or arguments; no child was spawned.

Io(Error)

Filesystem path resolution or metadata failed before execution.

NotExecutable

The selected file has no Unix executable permission bits.

Artifact(ArtifactError)

Executable identity could not be read or did not match authority.

Execution(Box<ExecutionError>)

One invocation failed; includes bounded evidence.

VersionUtf8

Successful version stdout was not valid UTF-8.

Fields

source: Utf8Error

UTF-8 validation failure.

evidence: Box<ExecutionEvidence>

Raw bounded version output.

VersionMismatch

Successful trimmed version stdout did not match the selected identity.

Fields

evidence: Box<ExecutionEvidence>

Raw bounded version output; never formatted into the error.

Implementations

impl ToolError

pub fn evidence(&self) -> Option<&ExecutionEvidence>

Borrow the original bounded capture, including successful version output.

Validation and filesystem/admission failures have no capture and return None. A failed spawn retains its existing empty execution evidence. No output is copied, decoded, logged or formatted by this accessor.

pub fn execution_error(&self) -> Option<&ExecutionError>

Borrow the original execution failure and its kill/reap outcomes, if any.

A successful version capture rejected by admission has evidence but no execution failure. Formatting, redaction and recovery remain caller-owned.

Trait Implementations

impl Debug for ToolError

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

Formats the value using the given formatter.

impl Display for ToolError

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

Formats the value using the given formatter.

impl Error for ToolError

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.
