Variants

Encoding

An error occurred decoding the header due to incorrect usage of text encoding by the sender.

RequestLineMalformed

The request line of the head part is malformed.

Fields

line: String

VersionMissing

The header first line does have a method and target URI, but it does not have a version, which is the required third part of the first line of the head.

Fields

line: String

StatusCodeMissing

The response status line does have a version, but does not have a status code which is required.

Fields

line: String

MethodUnknown

The specified method is not a valid method.

Fields

method: String

UriMissing

The header first line does have a method, but it does not have a target URI, which is the required second part of the first line of the head.

Fields

line: String

UriMalformed

The header first line has a Request-URI, but it could not be parsed correctly.

Fields

line: String

uri: String

UriNotAbsolute

The Request-URI is correct, but represents a relative path, which is not allowed in RTSP.

Fields

uri: Uri

ReasonPhraseMissing

The response status line has a version and status code, but is missing a reason phrase which is required.

Fields

line: String

VersionMalformed

The version specifier is incorrect. It should start with “RTSP/” followed by a digit, “.” and another digit.

Fields

line: String

version: String

StatusCodeNotInteger

The provided status code is not an unsigned integer or cannot be converted to one. It must be a 3-digit non-negative number.

Fields

line: String

status_code: String

HeaderMalformed

Header line is malformed.

Fields

line: String

ContentLengthMissing

The Content-Length header is missing, but it is required.

ContentLengthNotInteger

The Content-Length header is not an integer value, or cannot be converted to an unsigned integer.

Fields

value: String

HeadAlreadyDone

This occurs when the caller invokes the state machine with a state that signals that parsing the head part of the request was already done before.

BodyAlreadyDone

This occurs when the caller invokes the state machine with a state that signals that parsing the body part of the request was already done before.

MetadataNotParsed

Metadata was not parsed for some reason.

NotDone

This occurs when the caller tries to turn the parser into an actual request, but the parser was not ready yet.

VersionUnknown

This occurs when trying to serialize a request that does not have a known version.

TransportProtocolProfileMissing

Transport header does not have protocol and profile string. The transport must start with RTP/AVP, where RTP denotes the protocol and AVP the profile.

Fields

value: String

TransportLowerUnknown

Transport header contains unknown lower protocol. Use either TCP or UDP.

Fields

value: String

TransportParameterUnknown

Transport header contains unknown parameter. Please see RFC 2326 Section 12.39 for a list of permissable parameters.

Fields

var: String

TransportParameterValueMissing

Transport header contains parameter that should have a value, but does not have one.

Fields

var: String

TransportParameterValueInvalid

Transport header contains parameter with invalid value.

Fields

var: String

val: String

TransportParameterInvalid

Transport header contains invalid or malformed parameter.

Fields

parameter: String

TransportChannelMalformed

Transport header channel is malformed.

Fields

value: String

TransportPortMalformed

Transport header port is malformed.

Fields

value: String

InterleavedInvalid

Tried to parse interleaved data but there is no interleaved header. Interleaved packets always start with $ (0x24).

InterleavedPayloadTooLarge

Interleaved payload too large. The size cannot be larger than the maximum value of a 16-bit unsigned integer.

RangeMalformed

Range header value malformed.

Fields

value: String

RangeUnitNotSupported

Parser does not support provided Range header unit.

Fields

value: String

RangeTimeNotSupported

Parser does not support effective time in Range header.

Fields

value: String

RangeNptTimeMalfored

The NPT time (either the from or to part of the time specifier) is malformed.

Fields

value: String

RtpInfoUrlMissing

RTP Info must always contain a URL.

Fields

value: String

RtpInfoParameterUnknown

RTP Info parameter is not known. This means that the RTP part contains an unknown or non-existant parameter variable.

Fields

value: String

RtpInfoParameterInvalid

RTP Info parameter is invalid. This happens, for example, when the seq parameter is not an integer.

Fields

value: String

RtpInfoParameterUnexpected

RTP Info contains unexpected extra parameter.

Fields

value: String

Shutdown

Underlying socket was shut down. This is not really an error and consumers are expected to handle it gracefully.

Io(Error)

I/O error occurred.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, f: &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(error: Error) -> Self

Converts to this type from the input type.
