Implementations

impl SqlStatementRoute

pub const fn entity(&self) -> &str

Borrow the parsed SQL entity identifier for this statement.

SHOW ENTITIES does not carry an entity identifier and returns an empty string for this accessor.

pub const fn is_explain(&self) -> bool

Return whether this route targets the EXPLAIN surface.

pub const fn is_describe(&self) -> bool

Return whether this route targets the DESCRIBE surface.

pub const fn is_show_indexes(&self) -> bool

Return whether this route targets the SHOW INDEXES surface.

pub const fn is_show_columns(&self) -> bool

Return whether this route targets the SHOW COLUMNS surface.

pub const fn is_show_entities(&self) -> bool

Return whether this route targets the SHOW ENTITIES surface.

Trait Implementations

impl Clone for SqlStatementRoute

fn clone(&self) -> SqlStatementRoute

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SqlStatementRoute

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

Formats the value using the given formatter.

impl PartialEq for SqlStatementRoute

fn eq(&self, other: &SqlStatementRoute) -> 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.
