Enum Error

pub enum Error {
    MissingHeader(String),
    InvalidParam(String),
    ParseError(String),
    TokenizeError(String),
    Utf8Error(String),
    Unexpected(String),
}

The Error enum indicates that something went wrong

It has 6 variants:

• MissingHeader that a header that is expected to be found was completely missing. There are some headers that are required everywhere in SIP, like From, To etc.
• InvalidParam means some header parser did not succeed, and the reason for it is a missing or invalid parameter. Inner String should have the nom verbose error about it.
• ParseError indicates a general parsing error. Inner String should have the verbose nom error giving hints on what went wrong.
• TokenizeError indicates a general tokenizer error. Inner String should have the verbose nom error giving hints on what went wrong. A Tokenizer just tries to break the bytes into parts/components of rsip structs, but never tries to parse/convert to a specific type. So if a tokenizer fails and you get this error, it means it couldn’t even manage to break the SIP message in the correct breakpoints.
• Utf8Error indicates that the from_utf8 std method completely failed. At least you should get the information regarding which header had this issue.
• Unexpected indicates any other error.

Variants

MissingHeader(String)

InvalidParam(String)

ParseError(String)

TokenizeError(String)

Utf8Error(String)

Unexpected(String)

Implementations

impl Error

pub fn tokenizer<'a, S, T>(tuple: (S, T)) -> Self

where S: Into<String>, T: Into<&'a BStr>,

pub fn missing_header(header: &'static str) -> Self

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 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<Err<TokenizerError>> for Error

fn from(from: Err<TokenizerError>) -> Self

Converts to this type from the input type.

impl From<ParseIntError> for Error

fn from(error: ParseIntError) -> Self

Converts to this type from the input type.

impl From<TokenizerError> for Error

fn from(from: TokenizerError) -> Self

Converts to this type from the input type.

impl From<Utf8Error> for Error

fn from(error: Utf8Error) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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