pub struct SharedFactHeader {
    pub schema_version: u16,
    pub producer: String,
    pub kind: SharedFactKind,
    pub fact_id: u64,
    pub subject: u64,
    pub object: Option<u64>,

    pub soundness: Soundness,
}

Minimal cross-engine fact header.

Fields

schema_version: u16

Schema version, currently SHARED_FACT_SCHEMA_VERSION.

producer: String

Producer id such as c-c11, rustc-nll, or weir.

kind: SharedFactKind

Shared fact family.

fact_id: u64

Stable producer-local fact id.

subject: u64

Primary subject id.

object: Option<u64>

Optional object id.

aux: Option<u64>

Optional auxiliary id, usually a point, edge kind, or relation id.

file_id: u32

Stable file id, or zero when not source-spanned.

start_byte: u32

Start byte offset, inclusive.

end_byte: u32

End byte offset, exclusive.

soundness: Soundness

Soundness label for the fact.

Implementations

impl SharedFactHeader

pub fn new( producer: impl Into<String>, kind: SharedFactKind, fact_id: u64, subject: u64, soundness: Soundness, ) -> Self

Build one shared fact header.

pub const fn with_object(self, object: u64) -> Self

Attach an object id.

pub const fn with_aux(self, aux: u64) -> Self

Attach an auxiliary relation id.

pub const fn with_span( self, file_id: u32, start_byte: u32, end_byte: u32, ) -> Self

Attach a byte span.

pub fn wire_header(&self) -> String

Render the stable compact header used by schema contract tests.

Trait Implementations

impl Clone for SharedFactHeader

fn clone(&self) -> SharedFactHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SharedFactHeader

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SharedFactHeader

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for SharedFactHeader

impl PartialEq for SharedFactHeader

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
