Enum EntryState 

#[non_exhaustive]
pub enum EntryState {
    Written,
    Deleted,
    Unknown,
}

The state of a SEGB record.

Values are sourced from ccl_segb_common.py:EntryState:

Value	Name	Meaning
1	Written	Normal, live record
3	Deleted	Logically deleted record
4	Unknown	Placeholder / empty record (v2)

Unknown (4) in SEGB v2 marks a slot the code skips; it is exposed here so callers can observe it without the reader silently dropping the entry.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Written

Normal, live record. Value = 1.

Deleted

Logically deleted record. Value = 3.

Unknown

Empty placeholder (primarily SEGB v2). Value = 4.

Implementations

impl EntryState

pub fn from_raw(v: i32) -> Result<Self>

Decode from the raw i32 on-disk value.

pub fn is_live(self) -> bool

Return true if this is a live (Written) record.

Trait Implementations

impl Clone for EntryState

fn clone(&self) -> EntryState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for EntryState

impl Debug for EntryState

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

Formats the value using the given formatter.

impl Eq for EntryState

impl Hash for EntryState

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 EntryState

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