Enum ShowFunctionsFilter 

pub enum ShowFunctionsFilter {
    Name {
        like: bool,
        name: ObjectName,
        meta: Meta,
    },
    Regex {
        like: bool,
        pattern: Literal,
        meta: Meta,
    },
}

The optional trailing narrowing of a ShowTarget::Functions listing: [LIKE] {<function_name> | '<regex_pattern>'} (Spark / Databricks).

A distinct type from ShowFilter because that models MySQL’s mutually-exclusive LIKE '<pat>' | WHERE <expr> (a mandatory keyword, no bare-name form, and a WHERE predicate SHOW FUNCTIONS does not accept). Here the LIKE keyword is optional and the operand is either a bare (optionally qualified) function name or a quoted regex string; like records whether the keyword was written so the statement round-trips.

Variants

Name

[LIKE] <function_name> — a bare, optionally-qualified function name.

Fields

like: bool

Whether the optional LIKE keyword preceded the name.

name: ObjectName

The (optionally qualified) function name to match.

meta: Meta

Source location and node identity.

Regex

[LIKE] '<regex_pattern>' — a quoted regex-pattern string.

Fields

like: bool

Whether the optional LIKE keyword preceded the pattern.

pattern: Literal

The quoted regex-pattern string literal.

meta: Meta

Source location and node identity.

Trait Implementations

impl Clone for ShowFunctionsFilter

fn clone(&self) -> ShowFunctionsFilter

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)
