Implementations

impl FastlyStatus

pub const OK: Self = _

Success value.

This indicates that a hostcall finished successfully.

pub const ERROR: Self = _

Generic error value.

This means that some unexpected error occurred during a hostcall.

pub const INVAL: Self = _

Invalid argument.

pub const BADF: Self = _

Invalid handle.

Returned when a request, response, or body handle is not valid.

pub const BUFLEN: Self = _

Buffer length error.

Returned when a buffer is too long.

pub const UNSUPPORTED: Self = _

Unsupported operation error.

This error is returned when some operation cannot be performed, because it is not supported.

pub const BADALIGN: Self = _

Alignment error.

This is returned when a pointer does not point to a properly aligned slice of memory.

pub const HTTPINVALID: Self = _

Invalid HTTP error.

This can be returned when a method, URI, or header is not valid.

pub const HTTPUSER: Self = _

HTTP user error.

This is returned in cases where user code caused an HTTP error. For example, attempt to send a 1xx response code, or a request with a non-absolute URI. This can also be caused by an unexpected header: both content-length and transfer-encoding, for example.

pub const HTTPINCOMPLETE: Self = _

HTTP incomplete message error.

This can be returned when a stream ended unexpectedly.

pub const NONE: Self = _

A None error.

This status code is used to indicate when an optional value did not exist, as opposed to an empty value.

pub const HTTPHEADTOOLARGE: Self = _

HTTP head too large error.

This error will be returned when the message head is too large.

pub const HTTPINVALIDSTATUS: Self = _

HTTP invalid status error.

This error will be returned when the HTTP message contains an invalid status code.

pub const LIMITEXCEEDED: Self = _

Limit exceeded

This is returned when an attempt to allocate a resource has exceeded the maximum number of resources permitted. For example, creating too many response handles.

pub const AGAIN: Self = _

Resource temporarily unavailable

This is returned when an attempting to retrieve a resource that is not yet available. For example when attempting to read trailers from a Body that has not yet been consumed.

pub fn is_ok(&self) -> bool

pub fn is_err(&self) -> bool

pub fn result(self) -> Result<(), Self>

Convert a FastlyStatus value to a Result<(), FastlyStatus>.

This will consume a status code, and return Ok(()) if and only if the value was FastlyStatus::OK. If the status code was some error, then it will be returned in the result’s Err variant.

Trait Implementations

impl Clone for FastlyStatus

fn clone(&self) -> FastlyStatus

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FastlyStatus

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

Formats the value using the given formatter.

impl PartialEq for FastlyStatus

fn eq(&self, other: &FastlyStatus) -> 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.
