Struct LoadDataFields 

pub struct LoadDataFields {
    pub spelling: LoadFieldsSpelling,
    pub terminated_by: Option<Literal>,
    pub enclosed_by: Option<LoadDataEnclosed>,
    pub escaped_by: Option<Literal>,
    pub meta: Meta,
}

The {FIELDS | COLUMNS} … field-format clause of a LoadDataStatement (mysql sql_yacc.yy opt_field_term / field_term_list).

The FIELDS and COLUMNS keywords are interchangeable synonyms; the written spelling rides spelling so it round-trips. At least one of the three sub-clauses is present — a bare FIELDS with no sub-clause is ER_PARSE_ERROR (engine-measured), which the parser enforces. Each sub-clause may appear in any order and the parser folds it onto the matching field (a repeat is last-wins, mirroring the grammar’s merge_field_separators); the renderer emits the canonical TERMINATED / [OPTIONALLY] ENCLOSED / ESCAPED order.

Fields

spelling: LoadFieldsSpelling

The interchangeable keyword spelling (FIELDS vs COLUMNS); see LoadFieldsSpelling.

terminated_by: Option<Literal>

TERMINATED BY '<string>' — the field separator; None when absent.

enclosed_by: Option<LoadDataEnclosed>

[OPTIONALLY] ENCLOSED BY '<char>' — the field quoting; None when absent. See LoadDataEnclosed (the OPTIONALLY modifier rides it, so an OPTIONALLY without an ENCLOSED BY is unrepresentable).

escaped_by: Option<Literal>

ESCAPED BY '<char>' — the escape character; None when absent.

meta: Meta

Source location and node identity.

Trait Implementations

impl Clone for LoadDataFields

fn clone(&self) -> LoadDataFields

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LoadDataFields

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LoadDataFields

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for LoadDataFields

impl Hash for LoadDataFields

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)
