Enum ExecFailureKind 

pub enum ExecFailureKind {
    NotFound,
    PermissionDenied,
    NotExecutable,
    BadCwd,
    BadArgs,
    ResourceLimit,
    UserSetupFailed,
    OutOfMemory,
    PtySetupFailed,
    Other,
}

Coarse classification of an ExecFailed cause. The CLI’s stage-to-hint mapper keys off this; the SDK exposes it directly for programmatic consumers.

Variants

NotFound

Binary not found on PATH or at the explicit path. ENOENT on the binary path itself (not on the cwd — see BadCwd).

PermissionDenied

Binary found but not executable: EACCES or EPERM on file.

NotExecutable

File exists but the kernel can’t run it: bad ELF, missing interpreter for a shebang script, wrong architecture, etc. ENOEXEC.

BadCwd

Working directory unusable: doesn’t exist (ENOENT on cwd), not a directory (ENOTDIR), or no permission to chdir.

BadArgs

Argument or env list too large (E2BIG), too many symlinks resolving the path (ELOOP), path too long (ENAMETOOLONG), or invalid bytes in argv (e.g. interior NUL — EINVAL).

ResourceLimit

Resource limit prevented the spawn: rejected setrlimit (EPERM/EINVAL), per-process fork limit (EAGAIN with NPROC), fd table exhaustion (EMFILE/ENFILE).

UserSetupFailed

User/group setup failed: requested user doesn’t exist in the sandbox, or setuid/setgid rejected (EPERM).

OutOfMemory

Memory pressure: kernel couldn’t allocate (ENOMEM, or EAGAIN on fork without an explicit rlimit cause).

PtySetupFailed

PTY allocation or attachment failed (pty mode only).

Other

Anything else: errno is carried verbatim, message and stage describe the specifics.

Trait Implementations

impl Clone for ExecFailureKind

fn clone(&self) -> ExecFailureKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExecFailureKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ExecFailureKind

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ExecFailureKind

fn eq(&self, other: &ExecFailureKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ExecFailureKind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
