Struct DefinitionId 

pub struct DefinitionId(/* private fields */);

A tagged 64-bit identifier for any definition in a compiled story.

Layout: [tag: 8 bits][hash: 56 bits]

Implementations

impl DefinitionId

pub fn new(tag: DefinitionTag, hash: u64) -> Self

Create a new id from a tag and a 56-bit hash.

The hash is masked to 56 bits — upper bits are silently discarded.

pub fn tag(self) -> DefinitionTag

Extract the tag byte.

pub fn hash(self) -> u64

Extract the 56-bit hash.

pub fn to_raw(self) -> u64

Return the raw u64 representation.

pub fn from_raw(raw: u64) -> Option<Self>

Reconstruct from a raw u64, returning None if the tag byte is invalid.

Trait Implementations

impl Clone for DefinitionId

fn clone(&self) -> DefinitionId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DefinitionId

impl Debug for DefinitionId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DefinitionId

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for DefinitionId

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

Formats the value using the given formatter.

impl Eq for DefinitionId

impl Hash for DefinitionId

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 DefinitionId

fn eq(&self, other: &DefinitionId) -> 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 DefinitionId

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
