Implementations

impl SqlQueryKind

pub const fn as_str(self) -> &'static str

Returns the stable uppercase query kind label.

pub const fn is_read(self) -> bool

Returns whether the query kind is conservatively read-only.

pub const fn is_write(self) -> bool

Returns whether the query kind commonly mutates data or schema.

pub const fn is_schema_change(self) -> bool

Returns whether the query kind commonly changes schema.

pub const fn is_destructive(self) -> bool

Returns whether the query kind is conservatively destructive.

pub const fn intent(self) -> SqlQueryIntent

Returns a broad query intent label.

pub const fn safety(self) -> SqlQuerySafety

Returns a broad safety label.

pub fn classify(input: &str) -> Self

Classifies the first SQL-looking word without full parsing.

Trait Implementations

impl Clone for SqlQueryKind

fn clone(&self) -> SqlQueryKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SqlQueryKind

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

Formats the value using the given formatter.

impl Default for SqlQueryKind

fn default() -> SqlQueryKind

Returns the “default value” for a type.

impl Display for SqlQueryKind

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

Formats the value using the given formatter.

impl FromStr for SqlQueryKind

type Err = SqlQueryKindParseError

The associated error which can be returned from parsing.

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

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

impl Hash for SqlQueryKind

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 Ord for SqlQueryKind

fn cmp(&self, other: &SqlQueryKind) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for SqlQueryKind

fn eq(&self, other: &SqlQueryKind) -> 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 PartialOrd for SqlQueryKind

fn partial_cmp(&self, other: &SqlQueryKind) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
