Enum ProcedureLogLevel 

#[non_exhaustive]
pub enum ProcedureLogLevel {
    Debug,
    Info,
    Warning,
    Error,
}

The severity of a message a procedure body writes.

It is #[non_exhaustive]: a dialect matching on it states a fallback rather than assuming the list it compiled against is the list that ships. An engine with one logging statement and no levels — Oracle’s DBMS_OUTPUT is the worked case — ignores this and spells the message.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Debug

Detail wanted while diagnosing and not otherwise.

Info

The ordinary progress of a run, and the default.

Warning

Something worth a reader’s attention that did not stop the run.

Error

Something that went wrong. It is still a message and not a raise: a procedure that must stop uses SqlRenderer::render_procedure_raise.

Implementations

impl ProcedureLogLevel

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

The level’s own word, lower case — "debug", "info", "warning", "error".

An engine that takes a severity in its logging call reads it from here and spells it the way that call wants: SYSTEM$LOG('INFO', 'loaded') on Snowflake Scripting is level.as_str().to_uppercase().
