Struct CharsetAnnotation 

pub struct CharsetAnnotation {
    pub charset: Option<Charset>,
    pub name: Option<Ident>,
    pub binary: bool,
    pub meta: Meta,
}

A MySQL character-set type annotation carried by the string-typed DataType variants — Character, the Text LOB family, Enum, and Set (each engine-measured to admit it on mysql:8.4) — the grammar’s opt_charset_with_opt_binary production, part of the type rather than a column attribute (see the field docs on DataType::Character).

The canonical render emits the charset selector first, then BINARY (CHAR CHARACTER SET utf8mb4 BINARY); MySQL’s reversed spellings (CHAR BINARY CHARACTER SET utf8mb4, CHAR BINARY ASCII) fold onto this one shape, their exact written order recovered from the node span (an ADR-0011 spelling trade, mirroring the plural-interval and SIGNED INTEGER folds). The CHARSET synonym likewise folds to the canonical CHARACTER SET.

Fields

charset: Option<Charset>

The character-set selector, or None when only the BINARY collation modifier was written (CHAR BINARY, with no charset). At least one of charset / binary is always present — an empty annotation is None on the DataType::Character node.

name: Option<Ident>

The charset name for Charset::Named (CHARACTER SET <name> / CHARSET <name>); None for the keyword shortcuts (Charset::Ascii/Charset::Unicode/ Charset::Byte) and the bare-BINARY form. Held on this meta-bearing struct rather than inside the Charset enum so the tag stays a plain Copy kind. The name is a MySQL ident_or_text: a bare or backtick-quoted identifier, or a quoted string (CHARACTER SET 'utf8mb4'), whose spelling round-trips from the Ident’s quote style.

binary: bool

Whether the BINARY binary-collation modifier accompanies the annotation (CHAR BINARY, CHAR CHARACTER SET x BINARY, CHAR ASCII BINARY).

meta: Meta

Source location and node identity.
