Implementations

impl DialectId

pub fn upstream(self) -> Box<dyn Dialect>

Map a DialectId to the upstream sqlparser dialect used to parse it.

MariaDB intentionally returns MySqlDialect. We previously used a thin MariaDbDialect wrapper, but sqlparser gates many MySQL-only features (ON UPDATE timestamp column option, table hints, LIMIT a, b shorthand, etc.) behind dialect_of!(MySqlDialect) macros that downcast via Any. Any wrapper type, however faithful in trait forwarding, fails those is::<MySqlDialect>() checks and silently loses dozens of MySQL-superset features that MariaDB needs. Using MySqlDialect directly is the only reliable way to get the full MariaDB grammar parsed today; the application-level distinction is preserved via this DialectId enum.

MariaDB input is pre-processed by parse::parse to handle the bare --<EOL> comment form that real mariadb-dump output contains.

Trait Implementations

impl Clone for DialectId

fn clone(&self) -> DialectId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DialectId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DialectId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DialectId

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

Formats the value using the given formatter.

impl FromStr for DialectId

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for DialectId

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DialectId

fn eq(&self, other: &DialectId) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for DialectId

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
