Implementations

impl ParseError

pub fn too_large_header(current_size: usize, max_size: usize) -> Self

Creates a new TooLargeHeader error

pub fn too_many_headers(max_num: usize) -> Self

Creates a new TooManyHeaders error

pub fn invalid_header<S: ToString>(str: S) -> Self

Creates a new InvalidHeader error

pub fn invalid_body<S: ToString>(str: S) -> Self

Creates a new InvalidBody error

pub fn invalid_content_length<S: ToString>(str: S) -> Self

Creates a new InvalidContentLength error

pub fn io<E: Into<Error>>(e: E) -> Self

Creates a new I/O error

Trait Implementations

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Error for ParseError

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 ParseError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<ParseError> for HttpError

fn from(source: ParseError) -> Self

Converts to this type from the input type.
