Enum MultiBlockPresence

pub enum MultiBlockPresence {
    None,
    Some([u8; 16]),
    Full,
}

Summary information about the presence of multiple blocks belonging to a subtree.

Variants

None

All blocks missing

Some([u8; 16])

Some blocks present. The contained checksum is used to determine whether two subtrees have the same set of present blocks.

Full

All blocks present.

Implementations

impl MultiBlockPresence

pub fn is_outdated(&self, other: &Self) -> bool

pub fn checksum(&self) -> &[u8]

Trait Implementations

impl Clone for MultiBlockPresence

fn clone(&self) -> MultiBlockPresence

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MultiBlockPresence

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

Formats the value using the given formatter.

impl<'r> Decode<'r, Sqlite> for MultiBlockPresence

fn decode(value: SqliteValueRef<'r>) -> Result<Self, BoxDynError>

Decode a new value of this type using a raw value from the database.

impl<'de> Deserialize<'de> for MultiBlockPresence

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'q> Encode<'q, Sqlite> for &'q MultiBlockPresence

fn encode_by_ref( &self, args: &mut Vec<SqliteArgumentValue<'q>>, ) -> Result<IsNull, BoxDynError>

Writes the value of self into buf without moving self.

fn encode( self, buf: &mut <DB as Database>::ArgumentBuffer<'q>, ) -> Result<IsNull, Box<dyn Error + Send + Sync>>

where Self: Sized,

Writes the value of self into buf in the expected format for the database.

fn produces(&self) -> Option<<DB as Database>::TypeInfo>

fn size_hint(&self) -> usize

impl Hash for MultiBlockPresence

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 MultiBlockPresence

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Type<Sqlite> for MultiBlockPresence

fn type_info() -> SqliteTypeInfo

Returns the canonical SQL type for this Rust type.

fn compatible(ty: &<DB as Database>::TypeInfo) -> bool

Determines if this Rust type is compatible with the given SQL type.
