Expand description

Severity levels can used to be used to filter which messages get sent to a client.

The ordering of severity levels used for client-level filtering differs from the one used for server-side logging in two aspects: INFO messages are always sent, and the LOG severity is considered as below NOTICE, while it is above ERROR for server-side logs.

Variants§

Error

Sends only INFO, ERROR, FATAL and PANIC level messages.

Warning

Sends only WARNING, INFO, ERROR, FATAL and PANIC level messages.

Notice

Sends only NOTICE, WARNING, INFO, ERROR, FATAL and PANIC level messages.

Log

Sends only LOG, NOTICE, WARNING, INFO, ERROR, FATAL and PANIC level messages.

Debug1

Sends all messages to the client, since all DEBUG levels are treated as the same right now.

Debug2

Sends all messages to the client, since all DEBUG levels are treated as the same right now.

Debug3

Sends all messages to the client, since all DEBUG levels are treated as the same right now.

Debug4

Sends all messages to the client, since all DEBUG levels are treated as the same right now.

Debug5

Sends all messages to the client, since all DEBUG levels are treated as the same right now.

Info

Sends only NOTICE, WARNING, INFO, ERROR, FATAL and PANIC level messages. Not listed as a valid value, but accepted by Postgres

Implementations§

impl ClientSeverity

fn as_str(&self) -> &'static str

fn valid_values() -> Vec<&'static str>

pub fn should_output_to_client(&self, severity: &Severity) -> bool

Checks if a message of a given severity level should be sent to a client.

The ordering of severity levels used for client-level filtering differs from the one used for server-side logging in two aspects: INFO messages are always sent, and the LOG severity is considered as below NOTICE, while it is above ERROR for server-side logs.

Postgres only considers the session setting after the client authentication handshake is completed. Since this function is only called after client authentication is done, we are not treating this case right now, but be aware if refactoring it.
