Struct FieldData 

pub struct FieldData {
    pub field: SnapshotField,
    pub size_bytes: u64,
    pub checksum: u64,
    pub record_count: usize,
}

Metadata describing one field captured inside a StateSnapshot.

Fields

field: SnapshotField

Which logical field this record describes.

size_bytes: u64

Serialised byte size of the field payload.

checksum: u64

FNV-1a checksum of the field-name bytes.

record_count: usize

Number of logical records in the field (rules, facts, tensors, …).

Implementations

impl FieldData

pub fn new(field: SnapshotField, size_bytes: u64, record_count: usize) -> Self

Construct a FieldData, computing the checksum automatically from the canonical string name of the field.

Trait Implementations

impl Clone for FieldData

fn clone(&self) -> FieldData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldData

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

Formats the value using the given formatter.

impl PartialEq for FieldData

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