A serde-serializable error

Variants

ParseError

An error occurred in parsing the provided body content

Fields

path: String

the path of the parse error, as provided by serde_path_to_error

message: String

the contents of the error

IoError

A transmission error occurred in the connection to the http client

Fields

kind: String

stringified std::io::ErrorKind

message: String

stringified std::io::Error

UnsupportedMimeType

The client provided a content type that this library does not yet support

Fields

mime_type: String

the unsupported mime type

MissingContentType

The client did not provide a content-type

Other

Miscellaneous other errors – please open an issue on trillium-api if you find yourself parsing the contents of this.

Fields

message: String

A stringified error

FailureToNegotiateContent

we were unable to find a content type that matches the Accept header. Please open an issue if you’d like an additional format to be supported

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Error

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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 Status

fn from(value: &Error) -> Self

Converts to this type from the input type.

impl<E: Display> From<Error<E>> for Error

fn from(e: Error<E>) -> Self

Converts to this type from the input type.

impl From<Error> for Error

Available on crate feature sonic-rs only.

fn from(value: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(value: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

Available on crate feature forms only.

fn from(value: Error) -> Self

Converts to this type from the input type.

impl FromConn for Error

async fn from_conn(conn: &mut Conn) -> Option<Self>

returning None from this will not call the api handler, but will halt the conn.

impl Handler for Error

async fn run(&self, conn: Conn) -> Conn

Executes this handler, performing any modifications to the Conn that are desired.

async fn before_send(&self, conn: Conn) -> Conn

Performs any final modifications to this conn after all handlers have been run. Although this is a slight deviation from the simple conn->conn->conn chain represented by most Handlers, it provides an easy way for libraries to effectively inject a second handler into a response chain. This is useful for loggers that need to record information both before and after other handlers have run, as well as database transaction handlers and similar library code.

fn init(&mut self, info: &mut Info) -> impl Future<Output = ()> + Send

Performs one-time async set up on a mutable borrow of the Handler before the server starts accepting requests. This allows a Handler to be defined in synchronous code but perform async setup such as establishing a database connection or fetching some state from an external source. This is optional, and chances are high that you do not need this.

fn has_upgrade(&self, upgrade: &Upgrade) -> bool

predicate function answering the question of whether this Handler would like to take ownership of the negotiated Upgrade. If this returns true, you must implement [Handler::upgrade]. The first handler that responds true to this will receive ownership of the [trillium::Upgrade][crate::Upgrade] in a subsequent call to [Handler::upgrade]

fn upgrade(&self, upgrade: Upgrade) -> impl Future<Output = ()> + Send

This will only be called if the handler reponds true to [Handler::has_upgrade] and will only be called once for this upgrade. There is no return value, and this function takes exclusive ownership of the underlying transport once this is called. You can downcast the transport to whatever the source transport type is and perform any non-http protocol communication that has been negotiated. You probably don’t want this unless you’re implementing something like websockets. Please note that for many transports such as TcpStreams, dropping the transport (and therefore the Upgrade) will hang up / disconnect.

fn name(&self) -> Cow<'static, str>

Customize the name of your handler. This is used in Debug implementations. The default is the type name of this handler.

impl Serialize for Error

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
