Enum ServerDiscoveryError 

pub enum ServerDiscoveryError {
    InvalidRequestMetadata,
    InvalidCapabilityShape,
    TooManyExtensionSettings {
        actual: usize,
        maximum: usize,
    },

Why a server discovery value could not be safely constructed or admitted.

Variants

InvalidRequestMetadata

The request did not carry the required final request metadata.

InvalidCapabilityShape

A known capability field did not use its schema-required object shape.

TooManyExtensionSettings

The registry attempted to advertise more extension settings than allowed.

Fields

actual: usize

Observed extension setting count.

maximum: usize

Maximum allowed extension setting count.

InvalidExtensionName

An extension setting name was empty or exceeded its fixed bound.

Fields

length: usize

Observed UTF-8 byte length.

maximum: usize

Maximum allowed UTF-8 byte length.

ExtensionValueTooLarge

An extension setting value exceeded its exact JSON byte bound.

Fields

actual: usize

Observed encoded JSON byte length.

maximum: usize

Maximum allowed encoded JSON byte length.

ExtensionValueEncoding

An extension setting value could not be encoded as JSON.

Trait Implementations

impl Eq for ServerDiscoveryError

impl Error for ServerDiscoveryError

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 ServerDiscoveryError

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

Equality operator ==.

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

Inequality operator !=.
