Enum Definer 

pub enum Definer {
    Account {
        user: Ident,
        host: Option<Ident>,
        meta: Meta,
    },
    CurrentUser {
        parens: bool,
        meta: Meta,
    },
}

The MySQL DEFINER = <user> clause prefixing a routine (and, on other tickets, a view/trigger/event) definition — the account the object’s SQL SECURITY DEFINER context resolves to.

This is the measured minimal account surface the routine family needs: the bare <user>[@<host>] account name and the CURRENT_USER [()] self-reference, the two forms the corpus and the oracle exercise. The full MySQL account-name axis — the quoting-nuance matrix, role grants, and the IDENTIFIED BY authentication tail — is owned by parse-mysql-user-role-ddl; this node deliberately stops at the account reference a routine header carries, and that ticket widens it (or lifts it to a shared account node) without reshaping the routine statements that hold it.

Variants

Account

DEFINER = <user>[@<host>] — a named account. The user and optional host are each an Ident so both the bare (root) and quoted ('root'@'localhost') source spellings round-trip from their spans.

Fields

user: Ident

The account user name.

host: Option<Ident>

The optional @<host> part; None for a bare user with no host.

meta: Meta

Source location and node identity.

CurrentUser

DEFINER = CURRENT_USER [()] — the current user at definition time.

Fields

parens: bool

Whether the empty () call-style parentheses were written.

meta: Meta

Source location and node identity.

Trait Implementations
