Enum serenity::gateway::GatewayError

pub enum GatewayError {
    BuildingUrl,
    Closed(Option<CloseFrame<'static>>),
    ExpectedHello,
    HeartbeatFailed,
    InvalidAuthentication,
    InvalidHandshake,
    InvalidOpCode,

    NoAuthentication,

    OverloadedShard,
    ReconnectFailure,
    // some variants omitted
}

An error that occurred while attempting to deal with the gateway.

Note that - from a user standpoint - there should be no situation in which you manually handle these.

Variants

BuildingUrl

There was an error building a URL.

Closed(Option<CloseFrame<'static>>)

The connection closed, potentially uncleanly.

ExpectedHello

Expected a Hello during a handshake

HeartbeatFailed

When there was an error sending a heartbeat.

InvalidAuthentication

When invalid authentication (a bad token) was sent in the IDENTIFY.

InvalidHandshake

Expected a Ready or an InvalidateSession

InvalidOpCode

An indicator that an unknown opcode was received from the gateway.

InvalidShardData

When invalid sharding data was sent in the IDENTIFY.

Examples

Sending a shard ID of 5 when sharding with 3 total is considered invalid.

NoAuthentication

When no authentication was sent in the IDENTIFY.

NoSessionId

When a session Id was expected (for resuming), but was not present.

OverloadedShard

When a shard would have too many guilds assigned to it.

Examples

When sharding 5500 guilds on 2 shards, at least one of the shards will have over the maximum number of allowed guilds per shard.

This limit is currently 2500 guilds per shard.

ReconnectFailure

Failed to reconnect after a number of attempts.
