Struct CompilationFingerprint 

#[repr(transparent)]
pub struct CompilationFingerprint(pub Hash128);

Stable identity for a compiled query, keyed by the raw source text.

Used as the cache key for compiled instruction sequences, allowing identical query strings to skip parsing and planning.

Trait Implementations

impl Clone for CompilationFingerprint

fn clone(&self) -> CompilationFingerprint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

Returns the “default value” for a type.

impl Deref for CompilationFingerprint

type Target = u128

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'de> Deserialize<'de> for CompilationFingerprint

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<CompilationFingerprint> for Hash128

fn from(fp: CompilationFingerprint) -> Self

Converts to this type from the input type.

impl From<Hash128> for CompilationFingerprint

fn from(hash: Hash128) -> Self

Converts to this type from the input type.

impl From<u128> for CompilationFingerprint

fn from(value: u128) -> Self

Converts to this type from the input type.

impl Hash for CompilationFingerprint

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 CompilationFingerprint

fn cmp(&self, other: &CompilationFingerprint) -> 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,

impl PartialEq for CompilationFingerprint

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

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
