Enum Fault 

pub enum Fault {
    TooLarge {
        length: u32,
        limit: u32,
    },
    Empty,
    Cut,
}

Why a frame could not be read.

It is the cause inside the io::Error that read returns. A caller tells the causes apart with Fault::of, never by the error’s message. Each consumer decides its own policy for each.

Variants

TooLarge

The header names more bytes than the reader allows. Found on the header, before any body is allocated or read.

Fields

length: u32

limit: u32

Empty

The header names no bytes, so the frame has no tag.

Cut

The input ended inside the header or the body.

Implementations

impl Fault

pub fn of(error: &Error) -> Option<Self>

The fault a read error carries; None for an I/O failure that is not about the frame’s format.

Trait Implementations

impl Clone for Fault

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Fault

impl Debug for Fault

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

Formats the value using the given formatter.

impl Display for Fault

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

impl Eq for Fault

impl Error for Fault

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 PartialEq for Fault

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
