Unified error type for all rs-guard operations.

Variants

GitHubApi

GitHub REST API returned an error response.

Fields

status: u16

HTTP status code returned by GitHub (0 for connection/timeout failures).

message: String

Response body or description of the failure.

LlmApi

LLM provider API returned an error response.

Fields

provider: String

Name of the LLM provider (e.g. “deepseek”).

status: u16

HTTP status code returned by the provider (0 for connection/timeout failures).

message: String

Response body or description of the failure.

VerdictParse(String)

Failed to parse the verdict metadata block from an LLM response.

Tuple Fields

0: String

Description of the parsing failure.

Config(String)

Configuration is invalid or a required value is missing.

Tuple Fields

0: String

Description of the configuration problem.

Io(Error)

An I/O operation failed.

DiffTooLarge

The PR diff exceeds the maximum allowed size.

Fields

size_bytes: usize

Actual diff size in bytes.

line_count: usize

Actual diff line count.

EmptyDiff

The diff contained no content.

InvalidDiffContent

The diff response did not contain valid diff content (e.g. received JSON error body).

PermissionDenied

The GitHub token lacks permission to perform the requested review action.

Fields

state: String

The review state that was attempted (e.g. “APPROVE”).

message: String

Description of the permission failure.

Implementations

impl RsGuardError

pub fn is_retryable(&self) -> bool

Returns true if this error is transient and the operation should be retried.

Retryable conditions:

• HTTP 429 (rate limited), 502, 503, or 504
• Status 0 (connection error, timeout, DNS failure)

pub fn is_permission_denied(&self) -> bool

Returns true if this error indicates insufficient GitHub permissions.

Trait Implementations

impl Debug for RsGuardError

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

Formats the value using the given formatter.

impl Display for RsGuardError

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

Formats the value using the given formatter.

impl Error for RsGuardError

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.

impl From<Error> for RsGuardError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<LlmError> for RsGuardError

fn from(err: LlmError) -> Self

Converts to this type from the input type.
