Enum Error 

pub enum Error {
    Http(Error),
    NotFound(String),
    AccessEntityNotFound(String),
    AccessIdentityUnavailable,
    VersionNotFound(String, String),
    Unauthorized,
    Io(Error),
    RegistryWrite {
        status: u16,
        body: String,
    },
    Offline(String),
    InvalidName(String),
}

Variants

Http(Error)

NotFound(String)

AccessEntityNotFound(String)

AccessIdentityUnavailable

VersionNotFound(String, String)

Unauthorized

The registry rejected the request with 401/403 — either no auth token was configured, it was invalid, or the account doesn’t have permission for this package. Callers should point the user at aube login.

Io(Error)

RegistryWrite

Fields

status: u16

body: String

Offline(String)

InvalidName(String)

The caller passed a package name that does not match the npm name grammar. Returned eagerly (before any I/O) so a hostile packument or manifest cannot use the cache-path builder as an arbitrary-file-write primitive.

Implementations

impl Error

pub fn is_throttle(&self) -> bool

True when the error represents an upstream backpressure signal worth feeding into aube_util::adaptive::AdaptiveLimit::record_throttle. HTTP 429 / 502 / 503 / 504 and request timeouts qualify. Plain 4xx (NotFound, Unauthorized, ValidationError) and IO errors don’t — shrinking the concurrency cap won’t help those, and would over-react to transient hostile-input failures (a typo’d package name shouldn’t halve the limit).

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Diagnostic for Error

fn code(&self) -> Option<Box<dyn Display + '_>>

Unique diagnostic code that can be used to look up more information about this Diagnostic. Ideally also globally unique, and documented in the toplevel crate’s documentation for easy searching. Rust path format (foo::bar::baz) is recommended, but more classic codes like E0123 or enums will work just fine.

fn severity(&self) -> Option<Severity>

Diagnostic severity. This may be used by ReportHandlers to change the display format of this diagnostic.

fn help<'a>(&'a self) -> Option<Box<dyn Display + 'a>>

Additional help text related to this Diagnostic. Do you have any advice for the poor soul who’s just run into this issue?

fn url<'a>(&'a self) -> Option<Box<dyn Display + 'a>>

URL to visit for a more detailed explanation/help about this Diagnostic.

fn source_code(&self) -> Option<&dyn SourceCode>

Source code to apply this Diagnostic’s Diagnostic::labels to.

fn labels(&self) -> Option<Box<dyn Iterator<Item = LabeledSpan> + '_>>

Labels to apply to this Diagnostic’s Diagnostic::source_code

fn related<'a>( &'a self, ) -> Option<Box<dyn Iterator<Item = &'a dyn Diagnostic> + 'a>>

Additional related Diagnostics.

fn diagnostic_source(&self) -> Option<&dyn Diagnostic>

The cause of the error.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
