Enum CargoAllowErrorKind 

#[non_exhaustive]
pub enum CargoAllowErrorKind {
    Usage,
    InvalidConfig,
    InvalidPolicy,
    Inventory,
    Scan,
    PolicyViolation,
    Artifact,
    Internal,
    Unknown,
}

Structured kind for CargoAllowError, enabling programmatic consumers (CI tooling, sibling tools) to branch on error class instead of string-matching the rendered message.

This enum is #[non_exhaustive] so new kinds can be added without a breaking change for downstream library consumers.

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.

Usage

CLI usage error (bad flags, conflicting arguments).

InvalidConfig

Invalid or missing configuration file/values.

InvalidPolicy

Invalid policy ledger (validation failure, parse error, unknown field).

Inventory

Inventory discovery failure (git error, unreadable directory).

Scan

Scan failure (read error, parse error in a source file).

PolicyViolation

Policy violation (check/diff gate failed).

Artifact

Artifact or write failure (receipt rendering, policy write).

Internal

Internal invariant failure (should not happen).

Unknown

Unclassified — preserved for backward compatibility with new().

Implementations

impl CargoAllowErrorKind

pub const ALL: &[Self]

All error kinds currently defined by this version.

The enum is non-exhaustive; callers must still handle future kinds.

pub fn as_str(self) -> &'static str

Render the kind as a stable, lowercase identifier suitable for machine consumption (e.g. receipt error.kind fields).

pub const fn code(self) -> &'static str

Return the stable machine-readable error code for this kind.

Codes are part of the public contract and must not be reused for a different failure class. See docs/error-codes.md for the registry.
