Typed errors for library boundaries (thiserror).

Variants

InvalidSpec(String)

ArgvTooLarge

FC-66 — typed admission rejection for an over-sized spec.run.argv.

Surfaced by the FC-17 admission helper check_argv_size_within_kernel_cmdline_limit. The Firecracker host encodes spec.run.argv as cellos.argv=<base64(json_array)> on the kernel boot cmdline; the kernel cmdline has a 4 KiB hard limit and is silently truncated past that. We budget a 3 KiB cap on the encoded payload (≈1 KiB of headroom for the rest of the cmdline) and reject over-sized argv at admission so callers see a structured error rather than an opaque in-VM boot failure later.

encoded_bytes is the length of the base64-encoded JSON-array form of argv (i.e. exactly what the host would write into the cmdline). limit_bytes is the static cap (3072) so callers/operators do not have to dig into core to see the budget.

Trait Implementations

impl Debug for CellosError

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

Formats the value using the given formatter.

impl Display for CellosError

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

Formats the value using the given formatter.

impl Error for CellosError

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.
