Enum Error 

pub enum Error {
    Io(Error),
    Unsupported(String),
    InvalidData(String),
    Eof,
    NeedMore,
    FormatNotFound(String),
    CodecNotFound(String),

    Other(String),
}

Variants

Io(Error)

Unsupported(String)

InvalidData(String)

Eof

NeedMore

FormatNotFound(String)

CodecNotFound(String)

ResourceExhausted(String)

A decoder (or arena pool) refused to allocate or proceed because doing so would exceed a configured DecoderLimits cap, or because a pool has no free slot. This is the canonical “DoS protection fired” error — callers should treat it as a hard rejection of the input or a transient backpressure signal, never retry blindly.

Other(String)

Implementations

impl Error

pub fn unsupported(msg: impl Into<String>) -> Self

pub fn invalid(msg: impl Into<String>) -> Self

pub fn other(msg: impl Into<String>) -> Self

pub fn resource_exhausted(msg: impl Into<String>) -> Self

Construct a Error::ResourceExhausted with the given message. Use this from any decoder that has just hit a DecoderLimits cap or an arena-pool exhaustion.

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, __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 Error

fn from(source: Error) -> Self

Converts to this type from the input type.
